In Greek mythology, Niobe (Νιόβη) was the daughter of the semi-legendary ruler Tantalus, called the "Phrygian" and sometimes even as "King of Phrygia" Tantalus ruled in Sipylus, a city located at the western end of Anatolia. The city has the same name than the mountain on which it was founded (Mount Sipylus) and of which few traces remain, and not in the traditional heartland of Phrygia lying more inland and centered around Gordion. Niobe was an Anatolian princess. She married Amphion of Thebes and Greek mythology was a vehicle for her historical record mixed with legends. Niobe was the sister of Pelops, who gave his name to the Peloponnese.
