That is myth. There was no “rampant” homosexuality in either ancient or Hellenistic Greece.
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).
