Whatever may have been the origin of this legend, there seems no doubt that Siris was originally a city of the Chones, the native Oenotrian inhabitants of this part of Italy. A legend found in the Etymologicon, according to which the city derived its name from a daughter of Morges, king of the Siculi, evidently points in the same direction, as the Morgetes also were an Oenotrian tribe.
The origin of the story about Siris is uncertain, but it's clear that the city was originally inhabited by the Chones, the indigenous people of this part of Italy. A legend from a book called "Etymologicon" suggests that the name comes from a daughter of Morges, king of the Siculi, and supports the idea that the city was once home to the Morgetes, another Oenotrian tribe.
