We do not know whether the old Hellenes had any general word to denote the surrounding peoples ('Pelasgians and divers other barbarous tribes'[42:1]) whom they conquered or accepted as allies.[42:2] In any case by the time of the Persian Wars (say 500 b. c.) all these tribes together considered themselves Hellenized, bore the name of 'Hellenes', and formed a kind of unity against hordes of 'barbaroi' surrounding them on every side and threatening them especially from the east.
Let us consider for a moment the dates. In political history this self-realization of the Greek tribes as Hellenes against barbarians seems to have been first felt in the Ionian settlements on the coast of Asia Minor, where the 'sons of Javan' (Yawan = Ἰάων) clashed as invaders against the native Hittite and Semite. It was emphasized by a similar clash in the further colonies in Pontus and in the West. If we wish for a central moment as representing this self-realization of Greece, I should be inclined to find it in the reign of Pisistratus (560-527 b. c.) when that monarch made, as it were, the first sketch of an Athenian empire based on alliances and took over to Athens the leadership of the Ionian race.
In literature the decisive moment is clear. It came when, in Mr. Mackail's phrase, 'Homer came to Hellas'.[42:3] The date is apparently the same, and the influences at work are the same. It seems to have been under Pisistratus that the Homeric Poems, in some form or other, came from Ionia to be recited in a fixed order at the Panathenaic Festival, and to find a canonical form and a central home in Athens till the end of the classical period. Athens is the centre from which Homeric influence radiates over the mainland of Greece. Its effect upon literature was of course enormous. It can be traced in various ways. By the content of the literature, which now begins to be filled with the heroic saga. By a change of style which emerges in, say, Pindar and Aeschylus when compared with what we know of Corinna or Thespis. More objectively and definitely it can be traced in a remarkable change of dialect. The old Attic poets, like Solon, were comparatively little affected by the epic influence; the later elegists, like Ion, Euenus, and Plato, were steeped in it.[43:1]
In religion the cardinal moment is the same. It consists in the coming of Homer's 'Olympian Gods', and that is to be the subject of the present essay. I am not, of course, going to describe the cults and characters of the various Olympians. For that inquiry the reader will naturally go to the five learned volumes of my colleague, Dr. Farnell. I wish merely to face certain difficult and, I think, hitherto unsolved problems affecting the meaning and origin and history of the Olympians as a whole.
Herodotus in a famous passage tells us that Homer and Hesiod 'made the generations of the Gods for the Greeks and gave them their names and distinguished their offices and crafts and portrayed their shapes' (2. 53). The date of this wholesale proceeding was, he thinks, perhaps as much as four hundred years before his own day (c. 430 b. c.) but not more. Before that time the Pelasgians—i. e. the primitive inhabitants of Greece as opposed to the Hellenes—were worshipping gods in indefinite numbers, with no particular names; many of them appear as figures carved emblematically with sex-emblems to represent the powers of fertility and generation, like the Athenian 'Herms'. The whole account bristles with points for discussion, but in general it suits very well with the picture drawn in the first of these essays, with its Earth Maidens and Mothers and its projected Kouroi. The background is the pre-Hellenic 'Urdummheit'; the new shape impressed upon it is the great anthropomorphic Olympian family, as defined in the Homeric epos and, more timidly, in Hesiod. But of Hesiod we must speak later.
Now who are these Olympian Gods and where do they come from? Homer did not 'make' them out of nothing. But the understanding of them is beset with problems.
In the first place why are they called 'Olympian'? Are they the Gods of Mount Olympus, the old sacred mountain of Homer's Achaioi, or do they belong to the great sanctuary of Olympia in which Zeus, the lord of the Olympians, had his greatest festival? The two are at opposite ends of Greece, Olympus in North Thessaly in the north-east, Olympia in Elis in the south-west. From which do the Olympians come? On the one hand it is clear in Homer that they dwell on Mount Olympus; they have 'Olympian houses' beyond human sight, on the top of the sacred mountain, which in the Odyssey is identified with heaven. On the other hand, when Pisistratus introduced the worship of Olympian Zeus on a great scale into Athens and built the Olympieum, he seems to have brought him straight from Olympia in Elis. For he introduced the special Elean complex of gods, Zeus, Rhea, Kronos, and Gê Olympia.[45:1]
Fortunately this puzzle can be solved. The Olympians belong to both places. It is merely a case of tribal migration. History, confirmed by the study of the Greek dialects, seems to show that these northern Achaioi came down across central Greece and the Gulf of Corinth and settled in Elis.[45:2] They brought with them their Zeus, who was already called 'Olympian', and established him as superior to the existing god, Kronos. The Games became Olympian and the sanctuary by which they were performed 'Olympia'.[45:3]
