The lasso is a prop/tool to me - nothing to do with magical stories or foes or traits of Diana's (I mean, IIRC, it was just a gift from the others and its creation involved Greek goddesses). The transformation (if what I'm thinking of) was temporary and not particularly important. I don't recall seeing her ever work magic, particularly understand magic (again, outside the specific range of the Greek myths, which were always prominent), or fight magic much in the the oldest stories. So when did that start? Because in old stories, I would not have thought her connected to (generic, non Greek-mythology-based) magic any more than anyone else. I fully acknowledge that magic involving Greek Goddesses and Greek mythology has been there since day one. I was really thinking about when she became attached/connected to magic in the broader sense.
