As for the bisexuality, [historian Robin Lane] Fox says the historical accounts certainly support the love relationship between Hephaistion and Alexander. Homosexuality was an intricate part of the pre-Christian Greek world, well established, and sanctioned by state and cultural norms, especially the relationships between older men and teens. Where Alexander may have differed was that his affair with Hephaistion was lifelong and between men of roughly the same age.

It is fascinating, but unsurprising, that an ancient civilization was more advanced than ours in terms of tolerance for others.
