I've encountered a great deal of skepticism about the idea that the Sacred Band of Thebes was composed of male lovers. Were they composed of couples as many sources state, and if so, how does the Ancient Greek conception of same sex love between men compare with modern conceptions of sexual orientation?
Good question!
