That's a neato list, but I'm pretty sure the details of Crassus' death are reversed in your source - first it was the molten gold into the mouth, then the severing of the head... to retrieve the gold. I mean, what would be the point, or the punishment of pouring gold into his mouth after he was already dead?

And it was just "his enemies", it was King Orodes II of the Parthians, whose armies had defeated those of Crassus.
