however, sufficiently justified as a measure of Greek vengeance for the destruction by Xerxes of the temples in Greece, especially in Athens. While Alexander accomplished this great work—for he was the greatest individual at the head of Greece, he ever kept science and art in mind. Just as in modern times we have once more met with warriors who thought of science and of art in their campaigns, we also find that Alexander made an arrangement whereby whatever was discovered in the way of animals and plants in Asia should be sent to Aristotle, or else drawings and descriptions of the same. This consideration on Alexander’s part afforded to Aristotle a most favourable opportunity of collecting treasures for his study of nature. Pliny (Histor. natur. VIII., 17 ed. Bip.) relates that Alexander directed about a thousand men, who lived by hunting, fishing and fowling, the overseers of the zoological gardens, aviaries, and tanks of the Persian kingdom, to supply Aristotle with what was remarkable from every place. In this way Alexander’s campaign in Asia had the further effect of enabling Aristotle to found the science of natural history, and to be the author, according to Pliny, of a natural history in fifty parts. After Alexander commenced his journey to Asia, Aristotle returned to Athens, and made his appearance as a public teacher in the Lyceum, a pleasure-ground which Pericles had made for the exercising of recruits; it consisted of a temple dedicated to Apollo (Λύκειος), and shady walks (περίπατοι), which were enlivened by trees, fountains and colonnades. It was from these walks that his school received the name of Peripatetics, and not from any walking about on the part of Aristotle—because, it is said, he delivered his discourses usually while walking. He lived and taught in Athens for thirteen years. But after the death of Alexander there broke out a tempest which had, as it appeared, been long held back through fear of Alexander; Aristotle was accused of impiety. The facts are differently stated: amongst other things it is said that his hymn to Hermias and the inscription on the statue dedicated to him were laid to his charge. When he saw the storm gathering, he escaped to Chalcis in Eub\na, the present Negropont, in order, as he himself said, that the Athenians should not have an opportunity of once more sinning against Philosophy. There he died, in the next year, in the sixty-third year of his age, Ol. 114, 3 (322 B.C.).[83]
