According to legend, the way Pythagoras discovered that musical notes could be translated into mathematical equations

I heard on a radio 4 program, or something on the BBC I think, that he noticed it in grass / reeds, as they were waving in the wind like slowed down strings on instruments - and believed the patterns (of intervals, nodes, harmonics and so on) to be universal, music essentially.

I would be interested to chat with someone who understands superstring theory to a higher level than myself to know if the theory also allows for that in the model. If it does, he may have been laughably close to what's on the way, over two millenia ago (oldest scientific prediction that was correct?). :) — Preceding unsigned comment added by 86.166.134.7 (talk) 08:27, 23 June 2012 (UTC)

Deleted content

He was the first man to call himself a philosopher, or lover of wisdom. Many of the accomplishments of Plato, Aristotle and Copernicus were based on the ideas of Pythagoras. Unfortunately, very little is known about Pythagoras because none of his writings have survived. Many of the accomplishments credited to Pythagoras may actually have been accomplishments of his colleagues and successors.

I have deleted this.

The very first claim is specious at best, useless and confusing at worst: without being backed up by a clear primary source, there is no need to make a mention of it. It is also confusing, as we don't know whether a historical or a modern context is being put upon the term philosopher: 'philosophy' in the 6th Century BC referred to an investigator of natural principles (e.g. Thales, Anaximander, Democritus). Ipso facto, the person who wrote this may not be translating with a view to clarity: it would be far more clear for a reader today to be told that "he was the first man to call himself a scientist" or some other term approaching the idea of an investigator into nature. But even beside the contextual problems, why is this even noteworthy in an introductory paragraph? And is it true? Several other pre-Socratics approach calling themselves philosophers, as Heraclitus hints in writing that "men who are lovers of wisdom must be inquirers into many things." The second statement is a spill-over into the first statements mistake. Pythagoras had a strong influence upon Plato's metaphysics as well as later mathematicians and astronomers. That is not to say he made their achievements possible. The last two statements then contravene what the former two sentences have wagered. It is rather a mess.

I will keep this removed from the article until it is brought up to snuff or there is a robust reason for why it should be kept. across the synapse 19:04, 18 September 2007 (UTC)

See my comment immediately above yours. Primary sources for Pythagoras as introducer of philosophos include: Cicero, Tusculan Disputations, 5.3.8-9, Diog. Laert. 1.12, 8.8, Iamblichus VP 58. I've added the citations to the article & done a modest bit of additional pruning to reflect your concerns about some of what is admittedly crap in what you removed. But be more careful & less confident with "specious at best" etc.—the primary source for philosophos was in fact already included in the article's first footnote!

He was the first man to call himself a philosopher, or lover of wisdom

I saw this scentence and was wondering if we could authoritatively state that, before Pythagoras, nobody in the world called themselves a philosopher or a lover of wisdom. Instead of such a blanket statement, I felt a scentence that mentions this within the context of the reference material or of the region would be right.

Pythagoras in Miletos?

According to The Histories by the Herodotus, book V, chapter 126:

"126. This was the counsel of Hecataios; but Aristagoras was most inclined to go forth to Myrkinos. He therefore entrusted the government of Miletos to Pythagoras, a man of repute among the citizens, and he himself sailed away to Thrace, taking with him every one who desired to go; and he took possession of the region for which he had set out."

Herodotus mentions Pythagoras in his Book IV, chapter 92 as "Pythagoras the son of Mnesarchos". Therefore it looks like Pythagoras lived in Miletos, too.

First reference to Pythagoras in 2nd cent. CE?

This would explain the lack of reference to a man Pythagoras until 150 AD, given that he would have been of interest to contemporary philosophers (Aristotle referred to the so-called Pythagoreans).

What about Livy's (died 12/17 CE) mention of him? Roberts translation from Wikisource:

His master [Numa's] is given as Pythagoras of Samos, as tradition speaks of no other. But this is erroneous, for it is generally agreed that it was more than a century later, in the reign of Servius Tullius, that Pythagoras gathered round him crowds of eager students, in the most distant part of Italy, in the neighbourhood of Metapontum, Heraclea, and Crotona. (1.18)

Preceding unsigned comment added by 128.186.86.199 (talk) 20:52, 25 February 2008 (UTC)

And what about Heraclitus and Xenophanes--both contemporaries of Pythagoras who mentioned him (and apparently as a man--known to them by reputation if not in person):

[This book] (see p. 48 and following) goes into some depth about the references to Pythagoras in Xenophanes and some other contemporaries and near-contemporaries.

This paper talks about the Heraclitus/Pythagoras material:

“Heraclitus' Critique of Pythagoras' Enquiry in Fragment 129,” Oxford Studies in Ancient Philosophy 35 (2008), 19‑47.

The paragraph on sources is undoubtedly correct that later sources invent the "classical Pythagoras" and attribute to him all sorts of improbable things. But it's goes a little overboard when it suggests there are no references at all to Pythagoras as a person early on--even contemporary.

Bhugh (talk) 06:03, 15 February 2009 (UTC)

Very amusing notion, but Tyre was a Greek city on more than one occasion through time and was even shared by both "Greek" (actually several Hellenic peoples {plural}) and the Phoenicians who no longer viewed themselves as "upper Canaanites" (Tyre is not in upper Canaan). In fact the Phoenician queen hated Tyre so much (due to neighboring tribes) that they left and spread to new colonies. The Hellenic civilizations that traded with the Phoenicians were closely related, they were friendly over a long period of time and then it is well documented that they heavily intermarried. — Preceding unsigned comment added by 64.252.4.166 (talk) 04:02, 5 April 2013 (UTC)

There is of course no primary source for anything concerning Pythagoras but according to neo-Platonist Iamblichus of Chalcis not only was Pythagoras's father Phoenician but he was born in Sidon, not Samos. His father was, according to legend, made an honorary Samian when he brought a shipload of wheat to the island during a famine. Pythagoras traveled widely with his father, became interested in mathematics after meeting Thales of Miletos (a short hop away) and his pupil Anaximander, who advised him to further his learning in Egypt, of which the tyrant of Samos was an ally, where he managed to join a priesthood. When Cambyses II, successor of Cyrus, invaded Egypt, Pythagoras was taken prisoner to Babylon, where he continued his education. The Babylonians had discovered Phythagoras' theorem 1000 years before him but he apparently was able to prove it. Pythagoras probably enjoyed the good favors of his captors thanks to his fathers' being a Phoenician, since Phoenicia was an ally of Persia. When Darius captured Samos, Pythagoras returned there. However his elitist views, appreciated by former tyrant Polycrates, were rejected by the Samians and he was forced into exile. In conclusion, it was the wealth and connections of his Phoenician father, as well as the alliance of the local tyrant with Egypt, that made it possible for Pythagoras to accumulate and process all the mathematical knowledge of Egypt and Babylon. Just as up-and-coming young men in England would go on the "grand tour" of Europe to compensate for the deficiency in culture and learning in their own country, Pythagoras went on a grand tour of the centers of culture an civilization of the Iron Age and brought some of it back home. To pretend that it was the famine-racked backwater that was Samos in the 6th c. BC that miraculously produced this Da Vinci-like genius is simply ridiculous, unfortunately it is also conventional wisdom. Agitpapa (talk) 08:50, 14 July 2013 (UTC)

Just a postscriptum: The name of Samos is Phoenician, meaning "rise by the sea." It stands to reason that the island was colonized by the Phoenicians after the Greek dark ages, when Greeks even forgot how to read and write (and learned it all over again from the Phoenicians).

King Arthur

Read the article on King Arthur. Nowhere is the Arthurian legend presented as fact. The legend was created in romances over half a millenium after he was said to have lived. Those writing it knew it so, even if they prefaced it with "the following is based on real events from real history", Dan Brown stylee. Of course, there may have been a dude called Arthur, and he may have been a King, but if so, the Arthurian legend is no more likely to contain correct biographical facts about historical Arthur than a treatise on the tomato. If there are any, it is coincidence, not good history.

And yet the biographical facts in this article on Pythagoras are presented with authority. 'Pythagoras lived at 34 Greek Street' , 'Pythagoras liked to cut his sandwiches into triangles', 'Pythagoras invented playing cards'. Nobody knows! The legend of the dude Pythagoras was created by romantics 500 years later. These guys knew they were doing so. The story of the bean eating hippy Pythagoras is certainly a popular one to repeat, but not a real history. If there was a dude Pythagoras in the Pythagoreans , you are about as likely to find correct biographical facts about him in the article King Arthur than in this one.

Most of this article should be moved to the Pythagoreans, which also needs some scepticism. The bean-eating hippy legend can be repeated, but not presented as truth. Wikipedia, writing something down does not make it true. —Preceding unsigned comment addedby Matt me (talk • contribs) 10:08, 25 October 2008 (UTC)

Wrong. First, Pythagoras, his students, and the Pythagorans were very secretive because they believed their knowledge was not meant for the uninitiated and profane. Unlocking his and their history is very different than the development of the Arthurian legend. Second, "Philolaus, a not-so-secretive Pythagorean, wrote a book 50-75 years after Pythagoras death" - p.4, The Music of Pythagoras by Kitty Ferguson (Walker 2008). Third, There Are No Coincidences. Fourth, if you or anyone is going to criticize certain facts presented in this or any Wikipedia article, then refer to the exact statements, not your silly made-up ones, i.e. "Pythagoras lived at 34 Greek Street". And to refer to Pythagoras as a "hippy" is like referring to Jesus as a hippy; it's ignorant and very disrespectful of one of history's greatest and most influencial minds. - Brad Watson, Miami (talk) 13:52, 8 October 2012 (UTC)

Sarmoung Brotherhood

n Studies in Comparative Religion (Winter 1974), it is said that according to the Armenian book Merkhavat, the Sarmoung Brotherhood, also referred to as the 'Inner Circle of Humanity', originated in ancient Babylon circa 2500 BC,[2] at around the time the Egyptians built the Great Pyramid of Giza. The Ouspensky Foundation state that the brotherhood was active in the golden Babylonian time of Hammurabi (1728-1686 BC) and is connected with Zoroaster, the teacher of Pythagoras (born c. 580 BC–572 BC, died c. 500 BC–490 BC).

Clean-up attempt

I made a partial attempt to clean-up this article. I added a section on the (un)reliability of the sources to the top of the article. It's been taken from the beginning of the 1870 Dictionary of Greek and Roman Biography and Mythology article on Pythagoras. I rewrote the Life section; again, just pulling bits and bobs from the DGRBM article as I saw fit. I haven't done much to the rest of the article, although I deleted a couple of outlandish paragraphs and sentences, and I rearranged the article extensively. The section on Pythagoreans has no citations, and is a bit too uncritical for my tastes, but for now, I've moved it further down the article. This had the advantage of bringing the only really-well-written bit of the article upwards - the section on the Pythagorean theorem. Singinglemon (talk) 21:53, 8 September 2009 (UTC)

Well, since it had no references, I decided to rewrite the section on Pythagoreans as well, using some of the material which was there before. It's not great, but I hope the page as a whole, looks more reliable now. Singinglemon (talk) 21:13, 11 September 2009 (UTC)

Hi folks,

Furthur to my post about the yellow Pythagoras Theorem animation plus sign, which I now realise must have seemed somewhat ridiculous;

OK, sorry to doubt that you hadn't checked the article for simple errors... I do beg your pardon.

After first checking my own sanity, I have checked using another browser on my computer and indeed the sign is now shown as a strong black plus. It is also showing as a somewhat lighter plus sign when the gif is enlarged using the browser ( Safari 1.3.2 ) I originally viewed the article with. However, for some reason when the animation plays through in the small size at the side of the main article page using this browser version it shows as a minus sign - I kid you not. Changing screen resolution does not help. Perhaps it is something to do with the browser version not displaying the particular font characters correctly at small sizes.

Anyway, thanks for a great animation and your time. I'm just tucking into a large plate of humble pie.

I though Pythagoras was one of the most prominent early proponents of the Spherical Earth concept. If so, maybe we should mention that in the article about him. --Uncle Ed (talk) 19:05, 17 April 2010 (UTC)

There are almost no reliable facts known about what Pythagoras thought, and that's especially the case for the mathematical and scientific doctrines which were later fostered upon him. I see the Wikipedia page on the Spherical Earth does credit him with this. The idea apparently comes from Diogenes Laertius, viii. 48:

He [Pythagoras] was the first to call the heaven the universe and the earth spherical, though Theophrastus says it was Parmenides, and Zeno that it was Hesiod.

James Evans (The History and Practice of Ancient Astronomy, page 47) says about this passage: "the statements by later Greek writers merely reflect the propensity for attributing every discovery to one or another of their ancient wise men." Charles H. Kahn, (Pythagoras and the Pythagoreans: a brief history, page 53) just says that "the spherical earth is a distinctive innnovation of the Western [i.e. Magna Graecia ] cosmological tradition in Parmenides and Empedocles, whereas the Ionian tradition preserves the flat earth." Both Evans and Kahn agree that the idea may have originated in the Pythagorean school, but nothing more. We can add this to the page if you like, but with the health-warnings too. Singinglemon (talk) 15:48, 19 April 2010 (UTC)

Well I've not updated this page, but I've updated the page on the Spherical Earth to indicate the doubts about ascribing the idea to Pythagoras. Singinglemon (talk) 19:45, 19 April 2010 (UTC)

'Pythagorean motto': "God is ever a geometer"

In researching the history of Greek gematria - the alphanumeric quality of a language - we are pointed to Pythagoras and the Pythagoreans. There is an ancient Greek motto: "God is ever a geometer" (ἀεὶ ὁ Θεὸς ὁ μέγας γεωμετρεῖ), whereas, counting the letters of the words (3,1,4,1,5,9) reveals the first six digits of pi (3.14159). This confirms that 'Step 1' of Greek gematria is simply counting the number of letters in a word/name and that 'Step 2' is the gematric sum of a word/name. There's a question of whether "God is ever a geometer" is rightfully accredited to Pythagoras, the Pythagoreans, or to Plato? - Brad Watson, Miami, FL 65.34.180.54 (talk) 12:20, 15 May 2010 (UTC)

Pythagorean Hammers

I was having a difficult time finding anywhere on the internet the truth about the Pythagorean hammers; the story is clearly mythical, but everyone treats it as scientific truth (probably because the truth of the perfect proportions can be so easily demonstrated with strings that most people do not question whether the same would be true for hammers, or not). Anyway, fixed now, and I gave two sources. Terez27 (talk) 16:53, 2 January 2011 (UTC)

"This legend has since proven to be false by virtue of the fact that these ratios are only relevant to string length (such as the string of a monochord), and not to hammer weight.[48][49] However, it may be that Pythagoras was indeed responsible for discovering these properties of string length."

The ratios are not "only relevant to string length", but to vibrating air columns, such as in wind and brass instruments, and vibrating lengths of wood or metal, such as in xylophones, marimbas, vibraphones, accordions and harmonicas. Wind instruments have holes with or without keys to shorten and lengthen the air column to produce different pitches. Brass instruments often use valves to control the length of tube used to create an air column, and hence the basic pitch produced. Trombones vary the air column length with a telescopic slide - the more the slide is pulled out, the longer the column and thus the lower-pitched the basic note. By blowing into different holes in a harmonica, different lengths of metal (reeds) are vibrated to create different pitches. Accordions use bellows to vibrate the reeds, which are selected by keys or buttons. The longer the key on a xylophone, the lower-pitched the note it will produce when struck.

A common way to demonstrate the principle is to strike identical bottles containing different amounts of water; those with more water - and hence shorter air columns - will produce higher-pitched notes. The principle can also be readily seen in acoustic church organs, where the shorter the pipe, the higher the pitch it produces. JRalphS (talk) 15:03, 5 November 2012 (UTC)

i want to write the origination of phytagoras theorem that how dd it come into existence and how did he found that This is the origination:- One day phythagoras was drawing the same with some stick,he found that if a square is drawn on each side of 3-4-5 triangle,the area of the 2 small squares added together equals to the area of larger square He examined it with other right angle triangle and it true with them too.6²+8²=10² the set of 3 numbers viz (3,4,5) (6,8,10)(9,12,15)came to be know as phytagoras triplets

Pronunciation of Pythagoras ?

What's the English pronunciation of Pythagoras? (for those that haven't grown up in English) Any kind of IPA key seems to be missing. --Zom-B (talk) 05:09, 23 May 2012 (UTC)

....

The Right Angle Triangle Theorem is not his fuckin fathers property.

It is a classic geometrical relationship known to many cultures.

Which is why that fact is mentioned right there in the article. Please sign your contributions to talk pages, and try not to use them as a forum. Nczempin (talk) 15:14, 21 June 2012 (UTC)

"Everything is number" - Pythagoras

"Everything is number" is attributed to Phythagoras <ref]citation needed</ref]. Anybody got a good source for that? I'm working on it. - Brad Watson, Miami (talk) 14:04, 8 October 2012 (UTC)

Pythagoras' travels to India, Babylon, etc.

The old version of the page alleged that Diogenes mentions Pythagoras' travel to India, among other places. I have removed this, as such a mention (unless I have missed something!) does not appear in Diogenes, nor does it appear in Porphyry, nor does it appear in any other historian of antiquity. This entire idea seems to be based on the notion that Pythagoras must have gotten the idea for transmigration from somewhere, presumably India, but as far as I know no evidence directly supports this. Skadefryd (talk) 17:43, 23 October 2013 (UTC)

Diogenes Laërtius does say "he also journeyed among the Chaldaeans and Magi" -- so I'll add that quote to the page, since it at least implies journeys to places other than Egypt. As for the India claim, the only ancient source I can find is Apuleius, Florida, 15 [1], who talks about Pythagoras' visits to "the Brahmins, a race of wise men who live in India." Apuleius states that "it was from the Brahmins that he derived the greater part of his philosophy," and then goes on to give a list of doctrines, including of course the transmigration of souls. This is all pretty unlikely of course, but I guess there were some people in later antiquity ready to make the claim. Pasicles (talk) 22:57, 28 October 2013 (UTC)

Pythagorean theorum use prior to his time

Under the heading "Pythagorean Theorum" it says;

"While the theorem that now bears his name was known and previously utilized by the Babylonians and Indians..."

His theorum was also used in North America. Members of the Smithsonian, Squier and Davis, in 1848 surveyed constructions of the previous inhabitants of Ohio, known as the Hopewell civilasation (carbon-dating shows they were building and present in the eastern half of the USA as early as 5 500 BC). Some structures are perfect circles and squares. The surveyed constructions mentioned here are in Ohio but they were built after Pythagorus' time. But! That same civilization built using the same advanced maths up to 5 000 years earlier. Sorry to not give specific information on the 5 000 BC use of pythagorean theorem in northern america. I'm too tired to dig further at the moment.

Jim Viera has published on this and has been involved in a TED talk about the subject. He's well respected in this area.

Could someone verify the above and add on this page that it was "previously utilized by the Babylonians, Indians and ancient Americans"? Or something like that?

Source correction

In Section 6 Pythagoreans it reads "Both Plato and Isocrates affirm that, above all else, Pythagoras was famous for leaving behind him a way of life.[59]" Footnote 59 reads: "Plato, Republic, 600a, Isocrates, Busiris, 28" However I am studying Plato's Republic and decided to skip ahead to read 600a. Pythagorus is not mentioned until 600b. This is according the G.M.A. Grube translation.

I do not know if this is a small oversight of this page's editors or a difference in the numbering system of different translations but thought I'd bring it up since I saw it.
