It may therefore be inferred, that the epithet Πελασγικὸν is applied by Homer to the Thessalian vale collectively, as it is contained between the mountains of Pindus to the west, Œta and Olympus to the north, Othrys to the south, and Ossa or the sea to the east. We might, without geographical error, translate the phrase τὸ Πελασγικὸν Ἄργος of the second Iliad by that name of Thessaly[131], which the country afterwards acquired: but the idea which it properly indicates to us, is, _that Argos which had been settled by the Pelasgians_. It is the only geographical epithet which, applied to the name Argos, belongs to the north of Greece: and it is so applied by way of distinction and opposition to other uses of the name Argos in other parts of the poems, which we shall hereafter have to examine, namely, the Achaic and the Iasian Argos. _The Pelasgians: Dodona._ II. Perhaps the most solemn invocation of Jupiter as the great deity of the Greeks in the whole of the Poems is where Achilles, sending forth Patroclus to battle, prays that glory may be given him. It runs thus (Il. xvi. 233-5): Ζεῦ ἄνα, Δωδωναῖε, Πελασγικὲ, τηλόθι ναίων, Δωδώνης μεδέων δυσχειμέρου· ἀμφὶ δέ σ’ Ἕλλοι σοὶ ναίουσ’ ὑποφῆται ἀνιπτόποδες χαμαιεῦναι. It seems not too much to say upon this remarkable passage, that it shows us, as it were, the nation pitching its first altar upon its first arrival in the country. It bears witness that those who brought the worship of Dodonæan Jupiter were Pelasgians, as well as that the spot, which they chose for the principal seat of their worship, was Dodona. For the appeal of Achilles on this occasion is evidently the most forcible that he has it in his power to make, and is addressed to the highest source of Divine power that he knew. It has been debated, but apparently without any conclusive result, what was the site of the Dodona so famous in the after-times of Greece[132]. It seems clear, however, that it was a Dodona to the westward of Pindus, and belonging to Thesprotia or Molossia. But this plainly was not the position of the Dodona we have now before us. For in a passage of the Catalogue Homer distinctly places this Dodona in Thessaly, giving it the same epithet, δυσχείμερος, as Achilles applies to it in Il. xvi. Gouneus, he says, was followed by the Enienes and Perrhæbi, οἱ περὶ Δωδώνην δυσχείμερον οἴκι’ ἔθεντο, οἵ τ’ ἀμφ’ ἱμερτὸν Τιταρήσιον ἔργ’ ἐνέμοντο[133].
