Dionysiusthe Younger
Dionysius the Younger (367-343 B.C.) was chiefly noted for the excesses of his life. His brother-in-law and guardian Dion tried to reform him, and caused Plato to visit him more than once and exert his influence. But Dionysius banished Dion and confiscated his property. In 357 Dion made himself master of Syracuse, and Dionysius fled; but after the death of Dion he regained the power. Timoleon, who came from Corinth with aid against the Carthaginians, deposed him in 344. Dionysius went to Corinth, and is said there to have given lessons in grammar. He died in 343.
