The one with Justinian, correct? My personal impression is that while she was clearly very competent what with holding the empire together while he was busy surviving a disease with a 99.999% mortality rate, Justinian's primary reason for marrying her was that he was genuinely taken with her.
True, but she also came from waay lower on the social ladder than even the usual Lowborns. And you can't see people's stats in the real world anyway.
