Callisthenesof Olynthus

Callisthenes of Olynthus, philosopher and historian, accompanied Alexander the Great to India. He incurred Alexander's displeasure, and in 328 B.C. was executed on a charge of treason. Very little of his writings are extant, and the History of the Actions of Alexander ascribed to him is believed to belong to a later period.
