Argos Pelasgikon (Ancient Greek: Ἄργος Πελασγικόν) is a Homeric location of Thessaly mentioned in the "Catalogue of Ships" passage:[1] And with them were ranged thirty hollow ships.
Now all those again that inhabited Pelasgian Argos, and dwelt in Alos and Alope and Trachis, and that held Phthia and Hellas,[2] the land of fair women, and were called Myrmidons and Hellenes and Achaeans; of the fifty ships of these men was Achilles captain.
[3]It has been interpreted to be a city in the Pelasgiotis district or an alternative name of Phthia,[4] the kingdom of Peleus and Achilles or pertaining to the whole Thessaly.
[5] Strabo reports that: Some take the Pelasgian Argos as a Thessalian city once situated in the neighborhood of Larisa but now no longer existent; but others take it, not as a city, but as the plain of the Thessalians, which is referred to by this name because Abas, who brought a colony there from Argos, so named it[6].
Strabo gives also the following post-classical meaning of the word 'argos': And in the more recent writers the plain, too, is called Argos, but not once in Homer.
