- Alcmaeon of Croton
Alcmaeon (Gr. polytonic|Ἀλκμαίων) of Croton (in
Magna Græcia) was one of the most eminent natural philosophers and medical theorists of antiquity. His father's name was Pirithus, and he is said by some to have been a pupil of Pythagoras, and must therefore have lived in the latter half of the 6th century BC. Diogenes Laërtius, viii. 83] Although he wrote mostly on medical topics there is some suggestion that he was not a physician but a philosopher of science; he also indulged in astrologyand meteorology. Nothing more is known of the events of his life.cite encyclopedia | last = Greenhill | first = William Alexander | authorlink = | title = Alcmaeon (3) | editor = William Smith | encyclopedia = Dictionary of Greek and Roman Biography and Mythology| volume = 1 | pages = 104-105 | publisher = Little, Brown and Company| location = Boston | year = 1867 | url = http://www.ancientlibrary.com/smith-bio/0113.html ]
He was considered by many an early pioneer and advocate of anatomical
dissectionand was said to be the first to identify Eustachian tubes. His celebrated discoveries in the field of dissection were noted in antiquity, but whether his knowledge in this branch of science was derived from the dissection of animals or of human bodies is still a disputed question. ["Dict. of Ant.", p. 756, a] Calcidius, on whose authority the fact rests, merely says "qui primus exsectionem aggredi est ausus"," and the word "exsectio" would apply equally well in either case; [ Calcidius, "Comment. in Plat. "Tim." p. 368, ed. Fabr.] some modern scholars doubt Calcidius' word entirely.Citation | last = Owen | first = Gwilym Ellis Lane | author-link = | contribution = Alcmaeon (2) | editor-last = Hornblower | editor-first = Simon | title = Oxford Classical Dictionary| volume = | pages = | publisher = Oxford University Press| place = Oxford | year = 1996 | contribution-url = ]
He also was the first to dwell on the internal causes of illnesses. It was he who first suggested that health was a state of equilibrium between opposing humors and that illnesses were because of problems in environment,
nutritionand lifestyle. He is said also to have been the first person who wrote on natural philosophy (polytonic|φυσικὸν λόγον), [ Clement of Alexandria, "Strom." i. p. 308] and to have invented fables. ["fabulas", Isid. "Orig." i. 39] He also wrote several other medical and philosophical works, of which nothing but the titles and a few fragments have been preserved by Stobaeus, [ Stobaeus, "Eclog. Phys."] Plutarch, [ Plutarch, "De Phys. Philos. Decr."] and Galen. [ Galen, "Histor. Philosoph."] His "Concerning Nature" might be the earliest example of Greek medical literature.
He also contributed to the study of medicine by establishing the connection between the brain and the sense organs, and outlined the paths of the optic nerves as well as stating that the brain is the organ of the mind. However, his theories were not without mistakes. He said that sleep occurs when blood vessels in the brain are filled and that waking is caused by the emptying of these vessels. He also stated that the eye contains both fire and water. [Albert S. Lyons, M.D., F.A.C.S., R. Joseph Petrucelli,II, M.D., "Medicine: An Illustrated History", pp. 187, 192] [A further account of his philosophical opinions may be found in

Although Alcmaeon is often called a pupil of
Pythagoras, there is great reason to doubt whether he was a Pythagorean at all;cite encyclopedia | last = Jowett | first = Benjamin | authorlink = Benjamin Jowett | title = Alcmaeon (3) | editor = William Smith | encyclopedia = Dictionary of Greek and Roman Biography and Mythology| volume = 1 | pages = 105 | publisher = Little, Brown and Company| location = Boston | year = 1867 | url = http://www.ancientlibrary.com/smith-bio/0114.html ] his name seems to have crept into lists of Pythagoreans given us by later writers. Christian August Brandis, "Geschichte der Philosophie" vol. i. p. 507-508] Aristotlementions him as nearly contemporary with Pythagoras, but distinguishes between the "stoicheia" (polytonic|στοιχεῖα) of opposites, under which the Pythagoreans included all things; [ Aristotle, "Metaphysics" A. 5] and the double principle of Alcmaeon, according to Aristotle, less extended, although he does not explain the precise difference. Other doctrines of Alcmaeon have been preserved to us. He said that the human soul was immortal and partook of the divine nature, because like the heavenly bodies it contained in itself a principle of motion. [ Aristotle, "de Anima", i. 2, p. 405] [ Cicero, " De Natura Deorum" i. 11] The eclipseof the moon, which was also eternal, he supposed to arise from its shape, which he said was like a boat. All his doctrines which have come down to us relate to physics or medicine; and seem to have arisen partly out of the speculations of the Ionian School, with which rather than the Pythagorean, Aristotle appears to connect Alcmaeon, partly from the traditional lore of the earliest medical science.
