In the Ptolemaic period (350–30 BC), when Egypt became a Hellenistic kingdom ruled by Greek pharaohs, Anubis was merged with the Greek god Hermes, becoming Hermanubis.[27][28] The two gods were considered similar because they both guided souls to the afterlife.[29] The center of this cult was in uten-ha/Sa-ka/ Cynopolis, a place whose Greek name means "city of dogs." In Book XI of The Golden Ass by Apuleius, there is evidence that the worship of this god was continued in Rome through at least the 2nd century. Indeed, Hermanubis also appears in the alchemical and hermetical literature of the Middle Ages and the Renaissance.
