Cleitus the Black

Cleitus the Black (Ancient Greek: Κλεῖτος ὁ μέλας; c. 375 BC – 328 BC) was an officer of the Macedonian army led by Alexander the Great. He saved Alexander's life at the Battle of the Granicus in 334 BC, only to be murdered by him in a drunken quarrel six years later. Cleitus was the son of Dropidas and brother of Alexander's nurse, Lanike. He would be given the epithet 'the Black' to distinguish him from Cleitus the White.
