Strabo, Geography

As Homer frequently mentions the Spercheius as a river of the country, having its source in the Typhrestus, a Dryopian mountain, formerly called [Tymphrestus], and emptying itself near Thermopylæ, between Trachin and Lamia,¹ he might imply that whatever parts of the Maliac Gulf were either within or without the Pylæ, were subject to Achilles.

The Spercheius is distant about 30 stadia from Lamia, which lies above a plain, extending to the Maliac Gulf. That the Spercheius is a river of the country [subject to Achilles], appears from the words of Achilles, who says, that he had devoted his hair to the Spercheius; and from the circumstance, that Menesthius, one of his commanders, was said to be the son of Spercheius and the sister of Achilles.

It is probable that all the people under the command of Achilles and Patroclus, and who had accompanied Peleus in his banishment from Ægina, had the name of Myrmidons, but all the Phthiotæ were called Achæcans.
