Callisthenes

Callisthenes of Olynthus was a Greek historian in Macedon with connections to both Aristotle and Alexander the Great. He accompanied Alexander the Great during his Asiatic expedition and served as his historian and publicist. He later opposed Alexander’s adoption of Persian culture and was arrested after being implicated in a plot on the king's life; he died in prison. During his life, he authored several works on Greek history and a biography of Alexander the Great.
