LIFE OF HERACLIDES.
I. Heraclides was the son of Euthyphron, and was born at Heraclea, in Pontus; he was also a wealthy man.
II. After he came to Athens, he was at first a disciple of Speusippus, but he also attended the schools of the Pythagorean philosophers, and he adopted the principles of Plato; last of all he became a pupil of Aristotle, as we are told by Sotion in his book entitled the Successions.
III. He used to wear delicate garments, and was a man of great size, so that he was nicknamed by the Athenians Pompicus[53] instead of Ponticus. But he was of quiet manners and noble aspect.
IV. There are several books extant by him, which are exceedingly good and admirable. They are in the form of dialogue; some being Ethical dialogues; three on the subject of Justice; one on Temperance; five on Piety; one on Manly Courage; one, and a second which is distinct from it, on Virtue; one on Happiness; one on Supremacy; one on Laws and questions connected with them; one on Names; one called Covenants; one called The Unwilling Lover; and the Clinias.
Of the physical dialogues, one is on the Mind; one on the Soul; one on the Soul, and Nature and Appearances; one addressed to Democritus; one on the Heavenly Bodies; one on the State of Things in the Shades below; two on Lives; one on the Causes of Diseases; one on the Good; one on the doctrines of Zeno; one on the Doctrines of Metron.
Of his grammatical dialogues, there are two on the Age of Homer and Hesiod; two on Archilochus and Homer.
There are some on Music too; three on Euripides and Sophocles, and two on Music. There are also two volumes, Solutions of Questions concerning Homer; one on Speculations; one, the Three Tragedians; one volume of Characters; one dialogue on Poetry and the Poets; one on Conjecture; one on Foresight; four, being Explanations of Heraclitus; one, Explanations with reference to Democritus; two books of Solutions of Disputed Points; one, the Axiom; one on Species; one book of Solutions; one of Suppositions; one addressed to Dionysius.
