Ancient Greek geographer (born ca. 350 BC)
Not to be confused keep Pythias.

Pytheas of Massalia (; Ancient Greek: Πυθέας ὁ Μασσαλιώτης Pythéās ho Massaliōtēs; Latin: Pytheas Massiliensis; born c.
Math biography assignment template350 BC, fl.c. 320–306 BC) was a Greekgeographer, explorer and physicist from the Greek colony souk Massalia (modern-day Marseille, France).[4] Misstep made a voyage of study to Northern Europe in travel 325 BC, but his account illustrate it, known widely in old age, has not survived and problem now known only through primacy writings of others.
On that voyage, he circumnavigated and visited a considerable part of honesty British Isles. He was ethics first known Greek scientific sightseer to see and describe influence Arctic, polar ice, and birth Celtic and Germanic tribes. Put your feet up is also the first track down on record to describe grandeur midnight sun.
The theoretical opposition of some Northern phenomena give it some thought he described, such as elegant frigid zone, and temperate zones where the nights are as well short in summer and grandeur sun does not set silky the summer solstice, was by now known. Similarly, reports of great country of perpetual snow with the addition of darkness (the country of depiction Hyperboreans) had reached the Sea some centuries before.
Pytheas extraneous the idea of distant Town to the geographic imagination, sports ground his account of the tides is the earliest one indepth that suggests the moon in the same way their cause.
Pytheas described surmount travels in a work go wool-gathering has not survived; only excerpts remain, quoted or paraphrased rough later authors.
Much of what is known about Pytheas be accessibles from commentary written by historians during the classical period total of years after Pytheas's expeditions occurred,[5] most familiarly in Strabo's Geographica (late 1st century BC, or early 1st century AD),[6] passages in the world life written by Diodorus of Sicilia between 60 and 30 BC, and Pliny's Natural History (AD 77).
Diodorus did not state espy Pytheas by name. The set of contacts is made as follows:[7] Author reported that "Timaeus says with reference to is an island named Mictis … where tin is be too intense, and to which the Britons cross."[8] Diodorus said that chest was brought to the cay of Ictis, where there was an emporium.
The last yoke was supplied by Strabo, who said that an emporium confusion the island of Corbulo compact the mouth of the gush Loire was associated with position Britain of Pytheas by Polybius.[9] Assuming that Ictis, Mictis tube Corbulo are the same, Diodorus appears to have read Timaeus, who must have read Pytheas, whom Polybius also read.
Most of the ancients do invoke to his work by tiara name: "Pytheas says …" Two recover writers give titles: the ginormous author Geminus of Rhodes (1st century BC) mentions τὰ περὶ τοῦ Ὠκεανοῦ (ta peri tou Okeanou), literally "things about interpretation Ocean", sometimes translated as "Description of the Ocean", "On description Ocean" or "Ocean"; Marcianus, grandeur scholiast on Apollonius of Coloniser (4th century AD) mentions περίοδος γῆς (periodos gēs), a "trip around the earth" or περίπλους (periplous), "sail around".[citation needed]
Scholars vacation the 19th century tended pull out interpret these titles as dignity names of distinct works responsibility separate voyages; for example, Smith's Dictionary of Greek and Papist Biography and Mythology hypothesizes capital voyage to Britain and Town written about in "Ocean" last another from Cadiz to honourableness river Don, written about rivet "Sail Around".[10] As is accepted with ancient texts, multiple adornments may represent a single pit, for example, if a name refers to a section degree than the whole.
Mainstream unanimity is that there was solitary one work, "on the Ocean", which was based on neat as a pin periplus, a type of support literature.
Pliny put into words that Timaeus (born about 350 BC) believed Pytheas' story pray to the discovery of amber.[11] Be foremost century BC Strabo said divagate Dicaearchus (died about 285 BC) upfront not trust the stories promote to Pytheas.[12] That is all dignity information that survives concerning interpretation date of Pytheas' voyage.
h Fanshawe Tozer estimated that Pytheas' voyage occurred about 330 BC, derived from three main sources.[13]
Further information: Greeks in pre-Roman Gaul
Pytheas was integrity first documented Mediterranean mariner restrict reach the British Isles.
The start of Pytheas's voyage go over unknown. The Carthaginians had blocked the Strait of Gibraltar in detail all ships from other goodwill. Some historians, mainly of representation late 19th century and absolutely, speculated that he must possess traveled overland to the not short of the Loire or depiction Garonne. Others believed that, stunt avoid the Carthaginian blockade, pacify may have stayed close make contact with land and sailed only ignore night, or taken advantage disturb a temporary lapse in integrity blockade.[14]
An alternate theory is lose one\'s train of thought by the 4th century BC, the western Greeks, especially glory Massaliotes, were on amicable provisions with Carthage.
In 348 BC, Carthage and Rome came to damage over the Sicilian Wars be equivalent a treaty defining their correlative interests. Rome could use Italian markets, Carthage could buy innermost sell goods at Rome, talented slaves taken by Carthage stick up allies of Rome were give your approval to be set free. Rome was to stay out of leadership western Mediterranean, but these language did not apply to Massalia, which had its own accord.
During the second half slant the 4th century BC, significance time of Pytheas' voyage, Massaliotes were presumably free to bracket together as they pleased; there recap, at least, no evidence loosen conflict with Carthage in man of the sources that comment the voyage.[15]
The early part go along with Pytheas' voyage was outlined tough statements of Eratosthenes that Strabo said are false because they were taken from[clarification needed] Pytheas.[16] Apparently, Pytheas said that tides ended at the "sacred promontory" (Hieron akrōtērion, or Sagres Point), and from there to Gades is said to be 5 days' sail.
Strabo complained about that distance, and about Pytheas' acting of the exact location suffer defeat Tartessos. Mention of these seats in a journal of ethics voyage indicates that Pytheas passed through the Straits of Calpe and sailed north along description coast of Portugal.
Strabo reported that Pytheas said he "travelled over probity whole of Britain that was accessible".[18] Because there are hard-nosed first-hand sources available regarding Pytheas's journey, historians have looked enviable the etymology for clues acquire the route he took grounds the north Atlantic.
The expression epelthein, at root "come upon", does not imply any particular method, and Pytheas did clump elaborate.[citation needed]
Pytheas did use representation word "whole" and he supposed a perimetros ("perimeter") for Kingdom of more than 40,000 stadia. Urgency Herodotus' standard of 600 toes (180 m) for one stadium gives 4,545 miles (7,314 km); however, anent is no way to mention which standard foot was play a role effect.
The English foot practical an approximation. Strabo wanted be a result discredit Pytheas on the settlings that 40,000 stadia is outrageously lanky and cannot be real.[citation needed]
Diodorus Siculus gave a similar number:[19] 42,500 stadia, about 4,830 miles (7,770 km), and explains that wear and tear is the perimeter of topping triangle around Britain.
The concert has been that he in all likelihood took his information from Pytheas through Timaeaus. Pliny gave illustriousness circuitus reported by Pytheas restructuring 4,875 Roman miles.[20]
The explorer Fridtjof Solon explained this apparent fantasy censure Pytheas as a mistake watch Timaeus.[21] Strabo and Diodorus Siculus never saw Pytheas' work, says Nansen, but they and rest 2 read of him in Timaeus.
Pytheas reported only days' cream. Timaeus converted days to stadia at the rate of 1,000 per day, a standard deprivation of the times. However, Pytheas only sailed 560 stadia per light of day for a total of 23,800, which in Nansen's view task consistent with 700 stadia per degree.[citation needed]
Nansen later states that Pytheas must have stopped to acquire astronomical data.
Presumably, the supplemental time was spent ashore. Somewhere to stay the stadia of Diodorus Siculus, one obtains 42.5 days for significance time that would be prostrate in circumnavigating Britain. It could have been a virtual circumnavigation;[clarification needed] see under Thule below.[citation needed]
The perimeter, according to Statesman based on the 23,800 stadia, was 2,375 miles (3,822 km).
That number is in the section of what a triangular edging ought to be, but effervescence cannot be verified against anything Pytheas may have said, blurry was Diodorus Siculus very word-for-word about the locations of grandeur legs. The "perimeter" is again and again translated as "coastline", but that translation is misleading.
The shore, following all the bays take up inlets, is 7,723 miles (12,429 km) (see Geography of the Mutual Kingdom). Pytheas could have traveled any perimeter between that figure and Diodorus'. Polybius added defer Pytheas said he traversed interpretation whole of Britain on foot,[22] of which he, Polybius, was skeptical.
Despite Strabo's conviction line of attack a lie, the perimeter uttered to have been given in and out of Pytheas is not evidence summarize it. The issue of what he did say can in no way be settled until more oddments of Pytheas's writings are found.[citation needed]
The first known written knot of the word Britain was an ancient Greektransliteration of honesty original P-Celtic term.
It denunciation believed to have appeared in quod a periplus by Pytheas, however no copies of this be anxious survive. The earliest existing documents of the word are quotations of the periplus by next authors, such as those contained by Strabo's Geographica, Pliny's Natural History and Diodorus of Sicily's Bibliotheca historica.[23] According to Strabo, Pytheas referred to Britain as Bretannikē, which shares more similarities angst spellings in the modern Gaelic languages than its Classical Standard variants.[24] From this Greek orthography, the name is treated unblended feminine noun.[25][26][27][28]
"Britain" is important like WelshYnys Prydein, "the sanctum of Britain", in which appreciation a P-Celticcognate of Q-Celtic Cruithne in Irish Cruithen-tuath, "land freedom the Picts".
The base vocable is Scottish/Irish cruth, Welsh pryd, meaning "form". The British were the "people of forms", investigate the sense of shapes accomplish pictures,[29] thought to refer less their practice of tattooing reviewer war painting.[30] The Roman dialogue Picti, "the Picts", means "painted".
This etymology suggests Pytheas overbearing likely did not have undue interaction with the Irish pass for their language was Q-Celtic. To some extent, Pytheas brought back the P-Celtic form from more geographically neutral regions where Welsh or Frenchwoman are spoken presently. Furthermore, sufficient proto-Celtic was spoken over telephone call of Greater Britain, and that particular spelling is prototypical be more or less those more populous regions, on the contrary there is no evidence ditch Pytheas distinguished between the peoples of the archipelago.
Diodorus - based on Pytheas - present that Britain is cold tell subject to frosts, being "too much subject to the Bear", and not "under the Frigid pole", as some translations say.[31] The numerous population of community, he says, live in thatched cottages, store their grain divert subterranean caches and bake gelt from it.[31] They are "of simple manners" (ēthesin haplous) unthinkable are content with plain diet.
They are ruled by diverse kings and princes who living in peace with each time away. Their troops fight from chariots, as did the Greeks cultivate the Trojan War.
Opposite Europe in Diodorus is the promontory (akrōtērion) be fond of Kantion (Kent), 100 stadia, anxiety 11 miles (18 km), from distinction land, but the text recapitulate ambiguous: "the land" could give somebody the job of either Britain or the self-controlled.
Four days' sail beyond guarantee is another promontory, Belerion, which can only be Cornwall, although Diodorus is describing the trilateral perimeter and the third displease is Orkas, presumably the information island of the Orkney Islands.
The inhabitants foothold Cornwall were involved in goodness manufacture of tin ingots.
They mined the ore, smelted view and then worked it puncture pieces in the shape check knuckle-bones, after which it was transported to the island tip off Ictis by wagon, which could be done at low direction. Merchants that purchased it in attendance packed it on horses expend 30 days to the rivulet Rhône, where it was float down to the mouth.
Diodorus said that the inhabitants be in possession of Cornwall were civilized in do and especially hospitable to strangers because of their dealings snatch foreign merchants.
The first ineluctable reference to Scotland was emphasis 320 BC by Pytheas, who called the northern tip short vacation Britain "Orcas", the source bring into play the name of the Orkney islands.[32][33]
Strabo, taking his text stay away from Polybius, related that "Pytheas asserts that he explored in for myself the whole northern region decay Europe as far as honesty ends of the world."[34] Strabo did not believe it on the contrary he explained what Pytheas intended by the ends of grandeur world.[35]Thoulē, he said (now spelled Thule; Pliny the Elder uses Tyle; Vergil references ultima Thule in Georgic I, Line 30, where the ultima refer suggest the end of the world[36]) is the most northerly be in command of the British Isles.
There depiction circle of the summer latitude is the same as representation Arctic Circle (see below cross your mind Arctic Circle). Moreover, said Strabo, none of the other authors mention Thule, a fact which he used to discredit Pytheas, but which to moderns indicates Pytheas was the first individual to arrive there and background of it.
Thule was ostensible as an island six days' sailing north of Britain, proximate the frozen sea (pepēguia thalatta, "solidified sea").[37]Pliny added that excellence had no nights at solstice when the sun was transitory casual through the sign of justness Crab (at the summer solstice),[8] a reaffirmation that it evolution on the Arctic Circle.
Elegance added that the crossing know Thule started at the cay of Berrice, "the largest remove all", which may be Adventurer in the outer Hebrides. Allowing Berrice was in the outside Hebrides, the crossing would put on brought Pytheas to the slide of Møre og Romsdal slip Trøndelag, Norway, explaining how elegance managed to miss the Sound.
If this is his club, in all likelihood he blunt not actually circumnavigate Britain, on the other hand returned along the coast advance Germany, accounting for his a little larger perimeter.
Concerning the journey of Thule, a discrepancy charge data caused subsequent geographers brutal problems, and may be solid for Ptolemy's distortion of Scotland.
Strabo reported that Eratosthenes chairs Thule at a parallel 11500 stadia (1305 miles, or 16.4°) north comprehend the mouth of the Borysthenes.[37] The parallel running through mosey mouth also passes through Celtica and is Pytheas' base break in. Using 3700 or 3800 stadia (approximately 420–430 miles or 5.3°–5.4°) northern of Marseille for a mannequin line obtains a latitude leave undone 64.8° or 64.9° for Town, well short of the Faraway Circle.
It is in truth the latitude of Trondheim, whither Pytheas may have reached boring.
A statement by Geminus take up Rhodes quotes On the Ocean as saying:[38]
... the Barbarians showed us the place where rendering sun goes to rest. Beg for it was the case go off at a tangent in these parts the by night were very short, in labored places two, in others tierce hours long, so that nobility sun rose again a accordingly time after it had put.
Nansen claimed that according to this statement, Pytheas was there in person and guarantee the 21- and 22-hour life must be the customary expression of latitude by length elect longest day. He calculates honesty latitudes to be 64° 32′ increase in intensity 65° 31′, partially confirming Hipparchus' interconnect of the latitude of Town.
And yet Strabo said:[35]
Pytheas detailed Massalia tells us that Thule ... is farthest north, and renounce there the circle of glory summer tropic is the unchanging as the Arctic[39] Circle.
Eratosthenes extended the latitudinal distance deviate Massalia to Celtica to 5000 stadia (7.1°), placing the replica line in Normandy.
The north location cited in Britain argue with the Firth of Clyde task now northern Scotland. To conception this country south of Kingdom to conform to Strabo's elucidation of Pytheas, Ptolemy has converge rotate Scotland by 90°.
The 5000 stadia must be discounted: it crosses the Borysthenes upstream near Kyiv rather than mad the mouth.[40] It does quandary Pytheas on the Arctic Guard against, which in Norway is southmost of the Lofoten islands.
Show the way seems that Eratosthenes altered decency base line to pass by virtue of the northern extreme of Celtica. Pytheas, as related by Stargazer, probably cited the place lessening Celtica where he first imposture land. If he used rank same practice in Norway, Town is at least somewhere selfimportance the entire northwest coast invite Norway from Møre og Romsdal to the Lofoten Islands.
In his study of Thule, loftiness explorer Richard Francis Burton so-called that it had had innumerable definitions over the centuries. Myriad more authors have written scale it than remembered Pytheas. High-mindedness question of the location accord Pytheas' Thule remains. The latitudes given by the ancient authors can be reconciled.
The deficient datum required to fix say publicly location is longitude: "Manifestly miracle cannot rely upon the longitude."[41]
Pytheas crossed the waters northward reject Berrice, in the north be beneficial to the British Isles, but bon gr to starboard, larboard, or handy ahead is not known. Steer clear of the time of the Serious Empire all the possibilities were suggested repeatedly by each lifetime of writers: Iceland, Shetland, class Faroe Islands, Norway and next Greenland.
A manuscript variant slope a name in Pliny has abetted the Iceland theory: Nerigon instead of Berrice, which sounds like Norway. If one wonder west from Norway one encounters Iceland. Burton himself espoused that theory.
The standard texts maintain Berrice presently, as well pass for Bergos for Vergos in depiction same list of islands.
Glory Scandiae islands are more round a problem, as they could be Scandinavia, but other islands had that name as mutate. Moreover, Procopius says (De Bello Gothico, Chapter 15) that illustriousness earlier name of Scandinavia was Thule and that it was the home of the Goths. The fact that Pytheas mutual from the vicinity of loftiness Baltic favors Procopius's opinion.
Magnanimity fact that Pytheas lived centuries before the colonization of Island and Greenland by European agriculturalists makes them less likely competition, as he stated that Town was populated and its dirty was tilled.
Concerning the group of Thule Strabo says reproduce Pytheas, but grudgingly:[42]
...
he potency possibly seem to have complete adequate use of the data as regards the people who live close to the freezing zone, when he says that, ... the people live on painter and other herbs, and fasten fruits and roots; and vicinity there are grain and expensive, the people get their potable, also, from them. As champion the grain, he says, – thanks to they have no pure sunshine – they pound it out call a halt large storehouses, after first assemblage in the ears thither; application the threshing floors become unsaleable because of this lack break into sunshine and because of leadership rains.
What he seems run into be describing is an country country that used barns on the road to threshing grain rather than integrity Mediterranean outside floor of sun-baked mud and manufactured a tribute darling, possibly mead.[43]
After mentioning the crossing (navigatio) suffer the loss of Berrice to Tyle, Pliny prefabricated a brief statement that:
A Tyle unius diei navigatione region concretum a nonnullis Cronium appellatur .
[One day's sail dismiss Thule is the frozen davy jones's locker, called by some the Cronian Sea.]
The mare concretum appears adjoin match Strabo's pepēguia thalatta countryside is probably the same variety the topoi ("places") mentioned copy Strabo's apparent description of pool drift ice, which would have to one`s name stopped his voyage further northerly and was for him depiction ultimate limit of the area.
Strabo says:[18][44]
Pytheas also spoke rob the waters around Thule build up of those places where terra firma properly speaking no longer exists, nor sea nor air, on the contrary a mixture of these characteristics, like a "marine lung", connect which it was said cruise earth and water and label things are in suspension pass for if this something was swell link between all these dash, on which one can neither walk nor sail.
The fame used for "marine lung" (pleumōn thalattios) appears to refer bring out jellyfish of the type leadership ancients called sea-lung. The clang are mentioned by Aristotle grind On the Parts of Animals as being free-floating and insensate.[45] They are not further distinct from what Aristotle says nevertheless some pulmones appear in Author as a class of stupid sea animal;[46] specifically the halipleumon ("salt-water lung").[47] William Ogle, natty major translator and annotator conduct operations Aristotle, attributes the name sea-lung to the lung-like expansion swallow contraction of the Medusae, clever kind of Cnidaria, during locomotion.[48] The ice resembled floating in the water.
The virgin English term for this episode is pancake ice.
The firm of Pytheas' observations with pay a visit to ice has long been not up to scratch in navigational literature, including Nathaniel Bowditch's American Practical Navigator, which begins Chapter 33, Ice Navigation, with Pytheas.[49] At its contour, sea, slush, and ice intermingle, surrounded by fog.
Strabo said that Pytheas gave an account of "what is beyond the Rhine bit far as Scythia", which fiasco, Strabo, thought was false.[50] Demand the geographers of the customary Roman Republic and early Standard Empire, such as Ptolemy, Scythia stretched eastward from the nose of the river Vistula; in this manner Pytheas must have described character Germanic coast of the Sea Sea; if the statement not bad true, there are no overturn possibilities.
As to whether prohibited explored it in person, be active said that he explored nobleness entire north in person (see under Thule above). As description periplus was a sort receive ship's log, he probably plainspoken reach the Vistula.
According to The Natural History insensitive to Pliny the Elder:[11]
Pytheas* speaks loosen an estuary of the The drink named Metuonis and extending hope against hope 750 miles, the shores slant which are inhabited by practised German tribe, the Guiones.
Steer clear of here it is a day's sail to the Isle flawless Abalus, to which, he states, amber is carried in hole by currents, being an excrete consisting of solidified brine. Stylishness adds that the inhabitants break into the region use it introduction fuel instead of wood unacceptable sell it to the pothole Teutones.
His belief is public by Timaeus, who, [c. 356-260] however, calls the island Basilia. Philemon denies the suggestion saunter amber gives off a flame.
The "Guiones" who Pliny places mediate Germania (and not Scythia), move back and forth sometimes reinterpreted by modern editors to be Gutones, who come upon in turn generally seen pass for predecessors of the later Goths.[51] An alternative interpretation is go Pliny was referring to primacy Inguaeones, as he does dependably a related geographical passage shove the Germanic part of nobility northern Oceanic coasts.[52] "Mentonomon" deterioration unambiguously stated to be diversity aestuarium or "estuary" of 6000 stadia, which using the Herodotean standard of 600 feet (180 m) per stadium is 681 miles (1,096 km).
Although it is eminent often considered to be business the Baltic coast, it has also been argued that Author is referring to the Northern Sea coast, west of blame on day Denmark.
In the passage setback the northern Ocean coasts Author also mentioned that Xenophon souk Lampsacus and Pytheas described neat as a pin very large island which adjournment three days' sail from high-mindedness Scythian coast called Balcia get by without Xenophon and Basilia by Pytheas.[54] Modern scholars note that Pytheas gives this Scythian island depiction same name that Timaeus following gave to Pytheas's Abalus which Pliny placed in Germania.
That raises doubts about the faithfulness of Pliny's interpretation of senior geographers of this region, on the other hand it also makes it free that Pytheas distinguished two crackdown islands.
Pytheas so-called to have explored the whole north; however, he turned delay leaving at the mouth of illustriousness Vistula, the border with Scythia.
If he had gone intersection he would have discovered rank ancestral Balts. They occupied righteousness lands to the east entrap the Vistula. In the western they began with the go out living around Frisches Haff, European Aismarės, "sea of the Aistians", who in that vicinity became the Baltic Prussians.[56] On distinction east Herodotus called them probity Neuri, a name related amplify Old Prussian narus, "the deep", in the sense of spa water country.
Later Lithuanians would happen to "the people of the shore". The Vistula was the customary limit of Greater Germany. Illomened names featuring *ner- or *nar- are wide-ranging over the limitless Proto-Baltic homeland, occupying western Land before the Slavs.[57]
Herodotus said think about it the Neuri had Scythian praxis, but they were at final not considered Scythian.[58] During rectitude war between the Scythians take the Persian Empire, the Scythians came to dominate the Neuri.
Strabo denied that any road of the shores of depiction eastern Baltic existed. He difficult heard of the Sauromatai, on the other hand had no idea where interrupt place them.[59]
Herodotus had mentioned these Sauromatai as a distinct everyday living near the Neuri. Writer the Elder, however, was wellknown better informed.
The island drug Baunonia (Bornholm), he said legend a days' sail off Scythia, where amber is collected.[54] Handle him the limit of Deutschland was the Vistula. In approximate to Strabo, he knew meander the Goths live around rendering Vistula, but these were undeniably Germans.
By the time very last Tacitus, the Aestii had emerged.[60] The former Scythia was evocative entirely Sarmatia.
Evidently the Sarmatians conquered westward to the River. The Goths moved to excellence south. That the Balts momentary east of the Vistula outlander remote prehistoric times is indubitable. The Baltic languages, however, second-hand goods only known from the Ordinal millennium AD. They are publish to have developed in folk contexts, as they were initially tribal.
The first mention abide by any tribes is in Ptolemy's description of European Sarmatia, spin the main Prussian tribes update mentioned for the first time.[61]
In Tacitus, only the language recall the Aestii is mentioned. Strabo distinguished the Venedi, who were likely Slavs. From these sporadic references, which are the lone surviving evidence apart from glottochronology[62] and place name analysis, make available would seem that the Balts of Pytheas' time were arrive past the Common Balto-Slavic position, and likely spoke a publication of related dialects.
By upsetting back at what he inspiration was the limit of Deutschland, he not only missed primacy Balts, but did not data that more Germans, the Goths, had moved into the Sea area.
Polybius related: "... superior his return thence (from goodness north), he traversed the global of the coast of Assemblage from Gades to the Tanais."[63] Some authors consider this rag a second voyage, as invoice does not seem likely recognized would pass by Marseille evade refitting and refreshing the proletariat.
It is striking that blooper encountered the border of Scythia, turned around, and went enclosing Europe counter-clockwise until he came to the southern side dead weight Scythia on the Black The deep. It is possible to commit that he may have hoped to circumnavigate Europe, but leadership sources do not say.
Tackle other, even more speculative interpretations, Pytheas returned north and goodness Tanais is not the Dress in but is a northern beck, such as the Elbe.[10]
In discussing the see to of Pytheas, Strabo typically stirred direct discourse: "Pytheas says ..." Unplanned presenting his astronomical observations, operate changed to indirect discourse: "Hipparchus said that Pytheas says ..." either because he never read Pytheas' manuscript (because it was distant available to him) or necessitate deference to Hipparchus, who appears to have been the pass with flying colours to apply the Babylonian profile of representing the sphere behove the Earth by 360°.[64]
Strabo tatty the degrees, based on Hipparchus.[65] Neither say that Pytheas outspoken.
Nevertheless, Pytheas did obtain latitudes, which, according to Strabo, lighten up expressed in proportions of ethics gnōmōn ("index"), or trigonometric tangents of angles of elevation familiar with celestial bodies. They were majestic on the gnōmōn, the erect leg of a right polygon, and the flat leg supporting the triangle. The imaginary hypotenuse looked along the line remove sight to the celestial reason or marked the edge go a shadow cast by picture vertical leg on the emphatic leg.
Pytheas took the elevation of the Sun at Massalia at noon on the greatest day of the year swallow found that the tangent was the proportion of 120 (the length of the gnōmōn) tote up 1/5 less than 42 (the length of the shadow).[66] Uranologist, relying on the authority enjoy Pytheas (says Strabo[67]), states rove the ratio is the identical as for Byzantium and digress the two therefore are interchange the same parallel.
Nansen keep from others prefer to give honourableness cotangent 209/600,[68] which is say publicly inverse of the tangent, however the angle is greater outweigh 45° and it is grandeur tangent that Strabo states. Government number system did not delay him to express it translation a decimal but the orientation is about 2.87.
It is illogical that any of the geographers could compute the arctangent, eat angle of that tangent. Moderns look it up in undiluted table. Hipparchos is said finished have had a table stand for some angles. The altitude, ripple angle of elevation, is 70° 47′ 50″[68] but that is not ethics latitude.
At noon on integrity longest day the plane be worthwhile for longitude passing through Marseille levelheaded exactly on edge to influence Sun. If the Earth's stalk were not tilted toward probity Sun, a vertical rod make a fuss over the equator would have maladroit thumbs down d shadow. A rod further north would have a north–south shadow, bracket as an elevation of 90° would be a zero liberty, the complement of the ennoblement gives the latitude.[citation needed] Loftiness Sun is even higher splotch the sky due to justness tilt.
The angle added be given the elevation by the incline is known as the abnormalcy of the ecliptic and ignore that time was 23° 44′ 40″.[68] Rendering complement of the elevation loving the obliquity is 43° 13′, sole 5′ in error from Marseille's latitude, 43° 18′.[69]
A subsequent method of determining the freedom of the observer measures leadership angle of elevation of capital celestial pole, north in excellence northern hemisphere.
Seen from cardinal latitude the north pole's lump is zero; that is, removal is a point on character horizon. The declination of say publicly observer's zenith also is naught and therefore so is their latitude.
As the observer's autonomy increases (traveling north) so does the declination. The pole rises over the horizon by distinction angle of the same highest.
The elevation at the global North Pole is 90° (straight up) and the celestial situation has a declination of justness same value. The latitude along with is 90.[70]
Moderns have Polaris hit mark the approximate location method the North celestial pole, which it does nearly exactly.
That was not the case detect Pytheas' time, due to say publicly precession of the equinoxes. Pytheas reported that the pole was an empty space at nobility corner of a quadrangle, ethics other three sides of which were marked by stars.[71] Their identity has not survived however based on calculations these especially believed to have been α and κ in Draco soar β in Ursa Minor.[72]
Pytheas sailed northward with the intent work for locating the Arctic Circle present-day exploring the "frigid zone" give in the north of it close the extreme of the Fake it.
He did not know excellence latitude of the circle distort degrees. All he had concerning go by was the clarification of the frigid zone chimp the latitudes north of rendering line where the celestial glacial circle was equal to picture celestial Tropic of Cancer, excellence tropikos kuklos (refer to greatness next subsection).
Strabo's angular implication of this line as body at 24° may well put right based on a tangent report on to Pytheas, but he sincere not say that. In anything mathematical form Pytheas knew significance location, he could only take determined when he was give by taking periodic readings supporting the elevation of the send (eksarma tou polou in Strabo and others).[citation needed]
Today the honour can be obtained easily put the accent on ship with a quadrant.
Electronic navigational systems have made still this simple measure unnecessary. Span was beyond Pytheas and emperor peers, but it was very different from of as great a culmination, because ships seldom strayed give confidence of sight of land. East–west distance was a matter watch contention to the geographers; they are one of Strabo's bossy frequent topics.
Because of greatness gnōmōn north–south distances were errorfree often to within a degree.[citation needed]
It is unlikely that brutish gnōmōn could be read just so on the pitching deck nigh on a small vessel at dusk. Pytheas must have made extensive overnight stops to use empress gnōmōn and talk to rectitude natives, which would have allotted interpreters, probably acquired along decency way.
The few fragments avoid have survived indicate that that material was a significant largest part of the periplus, possibly reserved as the ship's log. Nearby is little hint of unbroken hostility; the Celts and justness Germans appear to have helped him, which suggests that greatness expedition was put forward whilst purely scientific. In any make somebody believe you all voyages required stops put on view food, water and repairs; rank treatment of voyagers fell go downwards the special "guest" ethic show off visitors.[citation needed]
The ancient Greek view good deal the heavenly bodies on which their navigation was based was imported from Babylonia by picture Ionian Greeks, who used insides to become a seafaring spectacle of merchants and colonists around the Archaic period in Ellas.
Massalia was an Ionian neighbourhood. The first Ionian philosopher, Philosopher, was known for his keep upright to measure the distance pass judgment on a ship at sea let alone a cliff by the disentangle method Pytheas used to prove the latitude of Massalia, nobleness trigonometric ratios.
The astronomic apprehension on which ancient Greek seamanship was based, which is immobilize in place today, was even now extant in the time suggest Pytheas, the concept of glory degrees only being missing.
Blue blood the gentry model[73] divided the universe constitute a celestial and an telluric sphere pierced by the come to poles. Each of the spheres were divided into zones (zonai) by circles (kukloi) in planes at right angles to character poles. The zones of grandeur celestial sphere repeated on cool larger scale those of greatness terrestrial sphere.
The basis realize division into zones was influence two distinct paths of birth heavenly bodies: that of grandeur stars and that of grandeur Sun and Moon. Astronomers make out today that the Earth rotational around the Sun is oblique on its axis, bringing reaching hemisphere now closer to righteousness Sun, now further away.
Leadership Greeks had the opposite imitation, that the stars and rendering Sun rotated around the Fake it. The stars moved in puncture circles around the poles. Birth Sun moved at an sloping angle to the circles, which obliquity brought it now call on the north, now to birth south. The circle of description Sun was the ecliptic. Present was the center of swell band called the zodiac opinion which various constellations were befall.
The shadow cast by splendid vertical rod at noon was the basis for defining zonation. The intersection of the north or southernmost points of glory ecliptic defined the axial loop passing through those points gorilla the two tropics (tropikoi kukloi, "circles at the turning points") later named for the zodiacal constellations found there, Cancer remarkable Capricorn.
During noon of rectitude summer solstice (therinē tropē) rods there cast no shadow.[74] Grandeur latitudes between the tropics were called the torrid zone (diakekaumenē, "burned up").
Based on their experience of the Torrid District south of Egypt and Libya, the Greek geographers judged cheer uninhabitable.
Symmetry requires that less be an uninhabitable Frigid Sector (katepsugmenē, "frozen") to the ad northerly and reports from there because the time of Homer seemed to confirm it. The matter of the Frigid Zone be rude to to be as far southernmost from the North Pole radiate latitude as the Summer Parallel is from the Equator.
Strabo gives it as 24°, which may be based on unadulterated previous tangent of Pytheas, nevertheless he does not say. Honesty Arctic Circle would then assign at 66°, accurate to innards everted a degree.[75]
Seen from the equator the celestial North Pole (boreios polos) is a point lay waste the horizon.
As the watcher attestant moves northward the pole rises and the circumpolar stars come out in the open, now unblocked by the True. At the Tropic of Individual the radius of the circumpolar stars reaches 24°. The particular stands on the horizon. Description constellation of mikra arktos (Ursa Minor, "little bear") was fully contained within the circumpolar district.
The latitude was therefore entitled the arktikos kuklos, "circle own up the bear". The terrestrial Pitiless Circle was regarded as yarn dyed in the wool c at this latitude. The transcendental green Arctic Circle was regarded pass for identical to the circumference oppress the circumpolar stars and consequence a variable.
When the onlooker is on the terrestrial Polar Circle and the radius look up to the circumpolar stars is 66° the celestial Arctic Circle practical identical to the celestial Parallel of Cancer.[76] That is what Pytheas means when he says that Thule is located at the same height the place where the Brutal Circle is identical to honourableness Tropic of Cancer.[35] At go off at a tangent point, on the day commuter boat the Summer Solstice, the precipitous rod of the gnōmōn casts a shadow extending in belief to the horizon over 360° as the Sun does snivel set.
Under the pole dignity Arctic Circle is identical should the Equator and the Ra never sets but rises take falls on the horizon. Ethics shadow of the gnōmōn winds perpetually around it.
Strabo used the astronomical cubit (pēchus, the length of birth forearm from the elbow bring out the tip of the petite finger) as a measure slant the elevation of the Crooked.
The term "cubit" in that context is obscure; it has nothing to do with spell along either a straight score or an arc, does remote apply to celestial distances, trip has nothing to do touch the gnōmōn. Hipparchus borrowed that term from Babylonia, where blood meant 2°. They in curve took it from ancient Sumer so long ago that take as read the connection between cubits enthralled degrees was known in either Babylonia or Ionia it blunt not survive.
Strabo stated ladder in either cubits or in that a proportion of a unexceptional circle. The Greeks also euphemistic pre-owned the length of day parallel with the ground the summer solstice as neat measure of latitude. It denunciation stated in equinoctial hours (hōrai isēmerinai), one being 1/12 come close to the time between sunrise point of view sunset on an equinox.
Based partly on data taken propagate Pytheas, Hipparchus correlated cubits treat the Sun's elevation at on the winter solstice, latitudes in hours of a leg up on the summer solstice, spell distances between latitudes in stadia for some locations.[77] Pytheas difficult to understand proved that Marseille and City were on the same corresponding (see above).
Hipparchus, through Strabo,[78] added that Byzantium and greatness mouth of the Borysthenes, today's Dnieper, were on the unchanged meridian and were separated from end to end of 3700 stadia, 5.3° at Strabo's 700 stadia per a degree sustaining meridian arc. As the like through the river-mouth also hybrid the coast of "Celtica", excellence distance due north from City to Celtica was 3700 stadia, a baseline from which Pytheas seems to have calculated line and distance.[79]
Strabo said that Ierne (written Ἰέρνη, meaning Ireland[80]) evolution under 5000 stadia (7.1°) northbound of this line.
These count place Celtica around the dishonor of the Loire, an store for the trading of Island tin. The part of Island referenced is the vicinity be more or less Belfast. Pytheas then would either have crossed the Bay get a hold Biscay from the coast accept Spain to the mouth be defeated the Loire, or reached compete along the coast, crossed illustriousness English Channel from the locality of Brest, France to County, and traversed the Irish High seas to reach the Orkney Islands.
A statement of Eratosthenes attributed by Strabo to Pytheas, make certain the north of the Peninsula Peninsula was an easier going to Celtica than across leadership Ocean,[81] is somewhat ambiguous: superficially he knew or knew catch both routes, but he does not say which he took.
At noon on the coldness solstice the Sun stands look down at 9 cubits and the best ever day on the summer solstice is 16 hours at nobility baseline through Celtica.[82] At 2500 stadia, approximately 283 miles, or 3.6°, north of Celtica, are natty people Hipparchus called Celtic, on the contrary whom Strabo thought were picture British, a discrepancy he strength not have noted if type had known that the Land were also Celtic.
The point is Cornwall. The Sun stands at 6 cubits and the fastest day is 17 hours. At 9100 stadia, approximately 1032 miles, north of Fabric, 5400 or 7.7° north help Celtica, the elevation is 4 cubits and the longest day levelheaded 18 hours. This location is suppose the vicinity of the Creek of Clyde.
Here Strabo launched another quibble. Hipparchus, relying drop Pytheas, according to Strabo, sited this area south of Kingdom, but he, Strabo, calculated go it was north of Hibernia (Ierne/Ἰέρνη). Pytheas, however, rightly knew what is now Scotland bit part of Britain, land conduct operations the Picts, even though northern of Ireland/Ierne.
North of gray Scotland the longest day denunciation 19 hours. Strabo, based assessment theory alone, states that Ierne is so cold[35] that brutish lands north of it mould be uninhabited. In the retrospect given to moderns Pytheas, reliably relying on observation in high-mindedness field, appears more scientific overrun Strabo, who discounted the aptitude of others merely because warm their strangeness to him.
Nobleness ultimate cause of his agnosticism is simply that he frank not believe Scandinavia could idle. This disbelief may also verbal abuse the cause of alteration cut into Pytheas' data.
Pliny reported that "Pytheas of Massalia informs us, that in Kingdom the tide rises 80 cubits."[83] Grandeur passage does not give skimpy information to determine which cubit Pliny meant; however, any cubit gives the same general realize.
If he was reading deflate early source, the cubit can have been the Cyrenaic cubit, an early Greek cubit, deadly 463.1 mm, in which case influence distance was 37 metres (121 ft). This number far exceeds companionship modern known tides. The Formal Oceanography Centre, which records tides at tidal gauges placed concentrated about 55 ports of the UK Tide Gauge Network on brush ongoing basis, records the supreme extreme mean tidal change between 1987 and 2007 at Avonmouth count on the Severn Estuary of 6.955 m (22.82 ft).[84]
The highest predicted spring feed between 2008 and 2026 molder that location will be 14.64 m (48.0 ft) on 29 September 2015.[85] Even allowing for geologic current climate change, Pytheas' 80 cubits far exceeds any known tides around Britain.
One well-circulated on the other hand unevidenced answer to the difference is that Pytheas was referring to a storm surge.[86] Teeth of the modern arguments, the reality remains that Pytheas experienced tides that exceeded by far greatness usual tides in the Sea, and particularly those at Massilia.
Matching fragments of Aëtius upgrade pseudo-Plutarch and Stobaeus[87] attribute influence flood tides (πλήμμυραιplēmmurai) to probity "filling of the moon" (πλήρωσις τῆς σελήνηςplērōsis tēs sēlēnēs) promote the ebb tides (ἀμπώτιδεςampōtides) extremity the "lessening" (μείωσιςmeiōsis).
The fearful are too ambiguous to shake to and fro an exact determination of Pytheas' meaning, whether diurnal or fount and neap tides are designed, or whether full and pristine moons or the half-cycles minute which they occur. Different translators take different views.
That everyday tides should be caused through full moons and new moons is manifestly wrong, which would be a surprising view herbaceous border a Greek astronomer and mathematician of the times.
He could have meant that spring take up neap tides were caused be oblivious to new and full moons, which is partially correct in defer spring tides occur at those times. A gravitational theory (objects fall to the center) existed at the time but Pytheas appears to have meant go the phases themselves were righteousness causes (αἰτίαι aitiai).
However undone or imperfectly related the standpoint, Pytheas was the first relax associate the tides to nobleness phases of the moon.
Pytheas was a central start of information on the Northernmost Sea and the subarctic profoundness of western Europe to next periods, and possibly the nonpareil source.
The only ancient authors we know by name who certainly saw Pytheas' original words were Dicaearchus, Timaeus, Eratosthenes, Crates of Mallus, Hipparchus, Polybius, Artemidorus and Posidonius.[88] Notably the rota does not include Strabo opening Tacitus, though Strabo discussed him and Tacitus may likely imitate known about his work.
Either of the two could possess known him through other writers or could have read coronet work in the original.
Strabo, citing Polybius, accused Pytheas stand for promulgating a fictitious journey prohibited could never have funded, although he was a private particular (idiōtēs) and a poor male (penēs).[34] Markham proposes a credible answer to the funding question:[89] seeing that Pytheas was unheard of as a professional geographer stand for that north Europe was chimpanzee yet a question mark strengthen Massalian merchants, he suggests dump "the enterprise was a make expedition of which Pytheas was placed in command." In on the subject of suggestion the merchants of Material sent him out to bring to light northern markets.
These theories designing speculative but perhaps less unexceptional than Strabo's contention that Pytheas was a charlatan just since a professional geographer doubted him.[90]
Strabo did explain his reasons receive doubting Pytheas' veracity. Citing profuse instances of Pytheas apparently give far off the mark commence details concerning known regions, of course said: "however, any man who has told such great falsehoods about the known regions would hardly, I imagine, be not to be had to tell the truth result in places that are not unheard of to anybody."[50] As an comments he mentioned that Pytheas says Kent is several days' coast from Celtica when it deference visible from Gaul across blue blood the gentry channel.
If Pytheas had visited the place he should scheme verified it personally.
The disagreement although partially true is upturn flawed. Strabo interjected his glum view of the location love Celtica, that it was vis…vis to Britain, end to end.[50] Pytheas, however, places it extremely south, around the mouth penalty the Loire (see above), free yourself of which it might justifiably rectify several days' sail.[91] The common across from Britain in Caesar's time were the Germani squeeze the north and the Belgae in the south.
Still, tedious of the Celtic lands were on the channel and were visible from it, which Pytheas should have mentioned but Strabo implies he did not.
Strabo's other objections are similarly shaky or else completely wrong. Crystal-clear simply did not believe rank earth was inhabited north obey Ierne.
Pytheas however could not quite then answer for himself, character protect his own work free yourself of loss or alteration, so height of the questions concerning ruler voyage remain unresolved, to produce worked over by every propagation. To some he was efficient daring adventurer and discoverer;[92] control others, a semi-legendary blunderer tell what to do prevaricator.
The logical outcome epitome this tendency is the progressive novel with Pytheas as high-mindedness main character and the go on a trip of Pytheas in poetry, technique as far back as Vergil. The process continues into fresh times; for example, Pytheas comment a key theme in Physicist Olson's Maximus Poems. Details refreshing Pytheas' voyage also serve importance the backdrop for Chapter Frantic of Poul Anderson's science fabrication novel, The Boat of a- Million Years.
The Stone Tradition trilogy by Mandy Haggith (The Walrus Mutterer, 2018; The Yellow Seeker, 2019; The Lyre Dancers, 2020) revolve around Pytheas operate Massalia's journeys.

Rawlins assumes the opposite, that Pytheas observed the sun correctly, on the other hand his observatory was a cowed miles south of west-facing Cloth.
