Note 23:1 — INTRODUCTION.[vii:1]

Dion obtained supreme power in Syracuse, though not the title of King, on the expulsion of Dionysius the younger. Callippus, his professed friend, was the leader of the band of malcontents that killed Dion, although he did not kill him with his own hand, perhaps shrinking from the act of murder on account of an oath which, when under suspicion, he had sworn at the altar of Persephone, that he would remain faithful to his friend. His aim was the place which Dion had held. It was his but a little while, and then, after a series of misfortunes and wanderings, he was killed at Rhegium with the same weapon that had been employed in the murder of Dion.
