expected. Not wishing at that time to
set up a rival school, he retired to the court of a former fellow-pupil,
Hermias, then king of Assos and Atarneus, whom he greatly respected, and
whose adopted daughter, Pythias, he later married. Here he remained,
pursuing his studies, for three years; and left only when his patron was
treacherously murdered by the Persians.

Having retired to Mitylene, he soon afterward received an invitation
from Philip of Macedonia to undertake the education of his son
Alexander, then thirteen years old. Aristotle willingly obeyed this
summons; and retiring with his royal pupil to Mieza, a town southwest of
Pella, imparted his instruction in the Nymphaeum, which he had arranged
in imitation of Plato's garden school. Alexander remained with him three
years, and was then called by his father to assume important State
duties. Whether Aristotle's instruction continued after that is
uncertain; but the two men remained fast friends, and there can be no
doubt that much of the nobility, self-control, largeness of purpose, and
enthusiasm for culture, which characterized Alexander's subsequent
career, were due to the teaching of the philosopher. What Aristotle was
in the world of thought, Alexander became in the world of action.

Aristotle remained in Macedonia ten years, giving instruction to young
Macedonians and continuing his own studies. He then returned to Athens,
and opened a school in the _peripatos_, or promenade, of the Lyceum, the
gymnasium of the foreign residents, a school which from its location was
called the Peripatetic. Here he developed a manifold activity. He
pursued all kinds of studies, logical, rhetorical, physical,
metaphysical, ethical, political, and aesthetic, gave public (exoteric)
and private (esoteric) instruction, and composed the bulk of the
treatises which have made his name famous. These treatises were composed
slowly, in connection with his lectures, and subjected to frequent
revision. He likewise endeavored to lead an ideal social life with his
friends and pupils, whom he gathered under a common roof to share meals
and elevated converse in common.

Thus affairs went on for twelve fruitful years, and might have gone on
longer, but for the sudden death of Alexander, his friend and patron.
Then the hatred of the Athenians to the conqueror showed itself in
hostility to his old master, and sought for means to put him out of the
way. How hard i
