Just skimming the first bit, there's some true info in the crazy. The Latin word for 'brothel' really is 'lupanar' and there really are a surprisingly large number of stone penises on the walls in the city. That the penises point anywhere is a popular myth, but isn't true; they were apparently good luck charms. Some of the houses had back doors, but it wasn't anywhere near all of them and there's no evidence they were intended for prostitution.

Skimming the rest looks like pure crazy, though.
