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].
Both the name of the Perrhæbi and that of the river Titaresius fix the Dodona of Homer in the north of Thessaly. And the character assigned to this Titaresius, so near Dodona, as a branch of Styx, ‘the mighty adjuration of the gods,’ well illustrates the close connection between that river, by which the other deities were to swear, and Jupiter, who was their chief, and was in a certain sense the administrator of justice among them. In the Odyssey, indeed, Ulysses, in his fictitious narrations to Eumæus and Penelope, represents himself as having travelled from Thesprotia to consult the oracle of Jupiter, that was delivered from a lofty oak[134]. But no presumption of nearness can be founded on this passage such as to justify our assuming the existence of a separate Dodona westward of the mountains in the Homeric age: and there was no reason why Ulysses should not represent himself as travelling through the passes of Mount Pindus[135] from the Ambracian gulf into Thessaly to learn his fate. Nor upon the other hand is there any vast difficulty in adopting the supposition which the evidence in the case suggests, that the oracle of Dodonæan Jupiter may have changed its seat before the historic age. The evidence of Homer places it in Thessaly, and Homer is, as we shall see, corroborated by Hesiod. After them, we hear nothing of a Dodona having its seat in Thessaly, but much of one on the western side of the peninsula. As in later times we find Perrhæbi and Dolopes to the westward of Pindus, whom Homer shows us only on the east, even so in the course of time the oracle may have travelled in the same direction[136]. It is highly improbable, from the manner in which the name is used, that there should have been two Greek Dodonas in the Homeric age.
However, the very passage before us indicates, that revolution had already laid its hand on this ancient seat of Greek religion. For though the Dodona of Homer was Pelasgic by its origin, its neighbourhood was now inhabited by a different race, the Selli or Helli, and these Helli were also the ὑποφῆται or ministers of the deity. While their rude and filthy habits of life mark them as probably a people of recent arrival, who had not themselves yet emerged from their highland home, and from the struggle with want and difficulty, into civilized life, still they had begun to encroach upon the Pelasgians with their inviting possessions and more settled habits, and had acquired by force or otherwise the control of the temple, though without obliterating the tradition of its Pelasgic origin. The very fact, that the Helli were at the time the ministers of Jupiter, tends to confirm the belief that the Pelasgians were those who originally established it; for how otherwise could the name of the Pelasgian race have found its way into an Hellenic invocation?
Thus, as before we found that what we term Thessaly is to Homer ‘the Argos of the Pelasgians,’ so we now find that people associated with the original and central worship of the Greek Jupiter, as having probably been the race to whom it owed its establishment.
And thus, though the Pelasgians were not politically predominant in Thessaly at the epoch of the Troica, yet Thessaly is Pelasgian Argos: though they were not possessed of the Dodonæan oracle, yet Jupiter of Dodona is Pelasgian Jupiter: two branches of testimony, the first of which exhibits them as the earliest known colonisers of the country, and the second as the reputed founders of the prime article of its religion.
