Making Assumptions.

I was watching a program on History Television Tuesday night about Cleopatra.  The comment was made that based on a modern reconstruction of what Cleopatra may have looked like Julius Caesar wouldn't have fallen for her because of her looks, because she wasn't hugely beautiful.  But how would anyone know that?  There's no way of knowing what Caesar thought was attractive in a woman.  It's not like he left an autobiography telling us what he found hot.
