This is possibly the only thing that Troy (2004) did kind of correctly. The architecture is full of nods to Hittite and New Kingdom Egyptian culture (look at the design of the temple of Apollo!), and the costuming also points to Hittite and Assyrian designs.
There's a ton of mystery surrounding the fall of Mycenaean civilization, but there's at least some general agreement that Troy was at least partially based on a real city (with a different name), and that they not only shared some gods/cults with Mycenae, but also might have been directly allied with Mycenaean kingdoms.
I don't think there's any reason to believe that there was no mixing of cultures between the Anatolian sphere and the Mycenaean sphere, considering that the entire Eastern Mediterranean was known to trade heavily (ESPECIALLY the sea focused Mycenaean's).
I don't think that's correct. It seems like it originated from a magical context: something that puts a sexual "spell" on you
