Alexander has a reputation as a big drinker. In one drunken incident, he argued with his friend and general Cleitus the Black (who had saved Alexander’s life many times), and killed him by throwing a javelin into his chest. There are some theories that alcoholism contributed to his early death.
Alexander the Great’s hair colour was reddish blond and that it curled naturally.
Alexander had tamed a wild horse named Bucephalus when he was a youth. He was so endeared to the animal that when it died, Alexander renamed a city in India for his beloved horse - Bucephala. (I couldn’t find if Bucephala still exists in some form in modern India; I doubt it does.)
Alexander the Great had heterochromia iridum; a condition in which the coloured part of the eye (iris) is multicoloured. Alexander had one blue eye, while the other was brown.
He was reported to have suffered from ailurophobia – the fear of cats.
One more thing…
Iron Maiden has a song which tells Alexander the Great’s life story.
