In later times, during the Ptolemaic period, as their functions were similar, Anubis came to be identified as the Greek god Hermes, becoming Hermanubis. The centre of this cult was in "uten-ha"/"Sa-ka"/ Cynopolis, a place whose Greek name simply means "city of dogs". In Book XI of "The Golden Ass" by Apuleius, we find evidence that the worship of this god was maintained in Rome at least up to the 2nd century. Indeed, it was revealed that Hermanubis also appeared in the alchemical and hermetical literature of the Middle Ages and the Renaissance.
