Easymo, I've never heard anything like that about Marcus Aurelius from a reliable source (please list if you have one). I've gotta admit that I doubt it. What I have seen is that every single Roman of note had some other Roman claiming that he fornicated with goats on the Appian Way. If you believe Procopious, you get a very twisted view of Justinian and Belisarious, and come away convinced that their wives ate babies on the walls of Constatinople before fornicating with goats.... Gave them strength.
Now that I re-read this, perhaps it's even relavent to the topic in a way. <grin>
