Hephaestion was the very close, personal friend & companion of which King?
Hephaestion Hephaestion Hephaestion ( "Hephaistíon"; c. 356 BC – 324 BC), son of Amyntor, was an ancient Macedonian nobleman and a general in the army of Alexander the Great. He was "by far the dearest of all the king's friends; he had been brought up with Alexander and shared all his secrets." This relationship lasted throughout their lives, and was compared, by others as well as themselves, to that of Achilles and Patroclus. His military career was distinguished. A member of Alexander the Great's personal bodyguard, he went on to command the Companion cavalry and was entrusted with many other tasks
Hephaestion was also his second in the political sphere. Alexander had made that official by naming him Chiliarch. Photius mentions Perdiccas being appointed "to command the chiliarchy which Hephaestion had originally held". Little is known of Hephaestion's personal relationships beyond his close friendship with Alexander. Alexander was an outgoing, charismatic man who had many friends but his dearest and closest friend and confidant was Hephaestion. Theirs was a friendship which had been forged in boyhood. It endured through adolescence, through Alexander's becoming king, and through the hardships of campaigning and the flatteries of court life and their marriages. Apart from Diogenes
