This then is the account of the several parts of Thessaly.

In general we say, that it was formerly called Pyrrhæa, from Pyrrha, the wife of Deucalion; Hæmonia, from Hæmon; and Thettalia, from Thettalus, the son of Hæmon. But some writers, after dividing it into two portions, say, that Deucalion obtained by lot the southern part, and called it Pandora, from his mother; that the other fell to the share of Hæmon, from whom it was called Hæmonia; that the name of one part was changed to Hellas, from Hellen, the son of Deucalion, and of the other to Thettalia, from Thettalus, the son of Hæmon. But, according to some writers, it was the descendants of Antiphus and Pheidippus, sons of Thettalus, descended from Hercules, who invaded the country from Ephyra in Thesprotia, and called it after the name of Thettalus their progenitor. It has been already said that once it had the name of Nessonis, as well as the lake, from Nesson, the son of Thettalus.
