Sorry, Nucsubs, but as a highly trained professional Art Historian, I beg to differ.
The Greeks idealized the man-boy love relationship to such an extent that they painted the pornographic subject on pottery. Lots of pottery. There are people who collect it (no doubt for the salaciousness of the subject), and in museums it is usually kept in the storage areas accessible only to staff. We unlucky few are, ahem, exposed to it. (Sorry for the pun.)
I take it from your handle that you were in the Nuclear Sub Fleet. I was, for six years, a Navy linguist (CTI).
Among particular social and economic cadres of the ancient world, there was certainly nothing deemed wrong with homosexual liaisons under accepted protocols. On the other hand, for the vast majority of rural folk in the Mediterranean world, heterosexuality and marriage were, of course, the norms. The pre-Christian poor and agrarian classes considered homosexual acts deviant, not on religious grounds of sinfulness, but rather as proof of corruption and decadence that were the wages of too much money and too much time in town.
This is merely the one quote I could find quickly online. I have read several books by him and he makes it quite clear that homosexuality was neither "rampant" nor celebrated. It was accepted in very narrow terms and considered a pathology of the very wealthy (hence the surviving art evidence you point to and the persistence of the myth). Your argument comes from the likes of Cahill who is a liberal hack next to Hanson.
