Euphrātes
（
Εὐφράτης).
1.
A native of Oreus in Euboea and a disciple of Plato. He quitted Athens for the court of
Perdiccas, king of Macedonia, with whom he became a favourite. After the death of this
monarch he returned to his country, and headed a party against Philip, the successor of
Perdiccas and father of Alexander. Being shut up, however, within the walls of Oreus, he put
an end to his own life. According to some, he was killed by order of Parmenio.
2.
A Stoic philosopher and native of Alexandria, who flourished in the second century. He was
a friend of the philosopher Apollonius of Tyana, who introduced him to Vespasian. Pliny the
Younger (
Epist. i. 10) speaks highly of his character. When he found his
strength worn out by disease and old age, he voluntarily put a period to his life by drinking
hemlock, having first, for some unknown reason, obtained permission from the emperor Hadrian.
