[Pyrrhic Dance], the chief war-dance of the Greeks, of quick, light movement to the music of flutes; was of Cretan or Spartan origin. It was subsequently danced for display by the Athenian youths and by women to entertain company, and in the Roman empire was a favourite item in the public games.

[Pyrrho], the father of the Greek sceptics, born in Elis, a contemporary of Aristotle; his doctrine was, that as we cannot know things as they are, only as they seem to be, we must be content to suspend our judgment on such matters and maintain a perfect imperturbability of soul if we would live to any good.

[Pyrrhonism], philosophic scepticism. See [Pyrrho].

[Pyrrhus], king of Epirus, and kinsman of Alexander the Great; essayed to emulate the Macedonian by conquering the western World, and in 280 B.C. invaded Italy with a huge army, directed to assist the Italian Greeks against Rome; in the decisive battles of that year and the next, he won "Pyrrhic victories" over the Romans, losing so many men that he could not pursue his advantage; 278 to 276 he spent helping the Greek colonies in Sicily against Carthage; his success was not uniform, and a Carthaginian fleet inflicted a serious defeat on his fleet returning to Italy; in 274 he was thoroughly vanquished by the Romans, and retired to Epirus; subsequent wars against Sparta and Argos were marked by disaster; in the latter he was killed by a tile thrown by a woman (318-272 B.C.).

[Pyrrhus], called also Neoptolemus, son of Achilles; was one of the heroes concealed in the wooden horse by means of which Troy was entered, slew Priam by the altar of Zeus, and sacrificed Polyxena to the manes of his father. Andromache, the widow of Hector, fell to him on the division of the captives after the fall of Troy, and became his wife.

[Pythagoras], a celebrated Greek philosopher and founder of a school named after him Pythagoreans, born at Samos, and who seems to have flourished between 540 and 500 B.C.; after travels in many lands settled at Crotona in Magna Græcia, where he founded a fraternity, the members of which bound themselves in closest ties of friendship to purity of life and to active co-operation in disseminating and encouraging a kindred spirit in the community around them, the final aim of it being the establishment of a model social organisation. He left no writings behind him, and we know of his philosophy chiefly from the philosophy of his disciples.

[Pythagoreans], the school of philosophy founded by Pythagoras, "the fundamental thought of which," according to [Schwegler], "was that of proportion and harmony, and this idea is to them as well the principle of practical life, as the supreme law of the universe." It was a kind of "arithmetical mysticism, and the leading thought was that law, order, and agreement obtain in the affairs of Nature, and that these relations are capable of being expressed in number and in measure." The whole tendency of the Pythagoreans, in a practical aspect, was ascetic, and aimed only at a rigid castigation of the moral principle in order thereby to ensure the emancipation of the soul from its mortal prison-house and its transmigration into a nobler form. It is with the doctrine of the transmigration of souls that the Pythagorean philosophy is specially associated.

[Pytheas], a celebrated Greek navigator of Massilia, in Gaul, probably lived in the time of Alexander the Great; in his first voyage visited Britain and Thule, and in his second coasted along the western shore of Europe from Cadiz to the Elbe.

[Pythian Games], celebrated from very early times till the 4th century A.D. every four years, near Delphi, in honour of Apollo, who was said to have instituted them to commemorate his victory over the Python; originally were contests in singing only, but after the middle of the 6th century B.C. they included instrumental music, contests in poetry and art, athletic exercises, and horse-racing.

[Python], in the Greek mythology a serpent or dragon produced from the mud left on the earth after the deluge of Deucalion, a brood of sheer chaos and the dark, who lived in a cave of Parnassus, and was slain by Apollo, who founded the Pythian Games in commemoration of his victory, and was in consequence called Pythius.
