This website seems to be willfully omitting the fact that the Sacred Band of Thebes was an elite military unit made up of 150 male lovers. Considering the stigma that pervades our culture that male homosexuals are weak and feminine, this is the ultimate history lesson to discredit such stereotypical and harmful prejudices. It is a discredit to the Bans that the authors seem to be sanitizing this incredible story so that it may be pandered to heteronormative sensabilities. Androkles & Kallistos are LOVERS. No one introduces their husband or wife as their "lifelong childhood friend."
If this is intended to be the least bit historically accurate, the author must take into account that the Sacred Band of Thebes was a unit made up solely of pairs of male lovers. Androkles and Kallistos would be together, not just friends. Regardless of varying opinions on homosexuality, historical accuracy is important.
