The Peneius rises, according to the Geographer, in that part of the Pindus Mountain about which the Perrhaebians live. . . . And Strabo also makes the following statements concerning the Peneius: The Peneius rises in the Pindus; and leaving Tricca on the left it flows around Atrax and Larissa, and after receiving the rivers in Thessaly passes on through Tempe. And he says that the Peneius flows through the center of Thessaly, receiving many rivers, and that in its course it keeps Olympus on the left and Ossa on the right. And at its outlets, on the right, is a Magnetan city, Gyrton, in which Peirithoüs and Ixion reigned; and not far from Gyrton is a city Crannon, whose citizens were called by a different name, "Ephyri," just' as the citizens of Gyrton were called "Phlegyae."
