that in creation the sun acted on the primitive miry earth, producing filmy bladders. These, becoming surrounded by a prickly rind, burst, and animals came forth. Man was first ejected as a fish. In this age Pythagoras taught that all things are constituted by the laws of Sacred Numbers, 54o B. C.
The phase of Grecian youth extended from Socrates to Epicurus, 341 B. C. Socrates taught that mathematics and physics lead to vain conclusions. His pupil, Plato, thinks that the senses are illusory, and he believes that God, Matter and Ideas are the three primary principles. Epicurus believed in pleasures through temperance, and rejects the doctrine of immortality. But it was in the domain of art that this age of Greece was to make its great and brilliant achievements. For several centuries the Greeks had carefully studied the external anatomy of man. They now showed the results in the first statuary and busts that had been correct in form and proportion. They imitated nature in her most graceful moods. In one age they passed from the rude copies of Egyptian or Etruscan art to the masterpieces of Phidias, Praxiteles, Polygnotus and Apelles. They carried art to that high state where it became the admiration of all succeeding ages. In architecture they give us beauty and grace and strength in the Corinthian, Ionic and Doric columns and capitals.
Maturity in Greece was ushered in by Aristotle, 384 B. C. He formulated the Inductive Method in Logic, and he taught that organic beings form a connected chain. But in physiology he thought that the brain is devoid of blood and of sensation. In this age Euclid develops geometry, 30o B. C., and Archimedes
