Well, physically, she may not have been his type, but I doubt she was as ugly as legend. I think she was simply provincial, lacking the knowledge of courtly games and languages and education that Henry expected his wives to have. She may have been intelligent, or even more beautiful than some of his wives, but she didn't have what he looked for in a woman, she wasn't sophisticated. She probably was both in looks and manner not what he expected, and no doubt if the alliance was unprofitable, this didn't help things, although even if she had brought a profitable alliance, one wonders if he would have had her as his wife.
