Of the posterity of the Homeric Prœtus we hear nothing, and with him the Danaid line, prolonged in a junior branch, may have expired. Tradition places him on the throne of Tiryns. His holding a separate sovereignty in Argolis is not of itself in conflict with the Homeric account of the Perseids, who reigned at Mycenæ; because we find in Argos itself a separate sovereignty under Diomed at the epoch of the Troica. But the terms used are peculiar. Prœtus ruled over Ἀργεῖοι;
πολὺ φέρτερος ἦεν
Ἀργείων· Ζεὺς γάρ οἱ ὑπὸ σκηπτρῷ ἐδάμασσεν[633].
The account of Eurystheus in the Nineteenth Book may, however, imply that he was king of all the Ἀργεῖοι: and at first sight there is some conflict here, because both Eurystheus and Prœtus may be said to date two generations before the Troica. The solution is probably as follows. The passion of Antea, wife of Prœtus, for Bellerophon, suggests that her husband was more advanced in life than Bellerophon, whom, as the grandfather of Glaucus, we may take as justly representing in time the second generation before the war. On the other hand, as Eurystheus was the contemporary of Hercules, and Hercules had a son, as well as grandsons in the war, we may assume Eurystheus to have been junior to the generation, as Prœtus was its senior; so that they need not have been contemporary princes.
The historic place assigned to Danaus, either as we might fix it from Homer, or as the later tradition would determine it, keeps him clear of the earliest Hellic traditions in southern Greece. None of these can well be carried back beyond Sisyphus; and Sisyphus stands at five generations before the war, while Danaus cannot be less than seven. Had Homer made Danaus synchronise with the earlier Hellic sovereignties, it would have been, in my view, a presumption against his Egyptian origin, or his existence altogether. For an Egyptian stranger was little likely to attain to power, where Hellenes were already in the field: the more energetic genius would subdue the less vigorous. The expulsion of the Hellenic Bellerophon, and the plot against his life, may really have been connected with the political jealousies of the Danaids towards the formidable new-comers of the Æolid stem: nor do I read the fable of Jupiter with Danae otherwise than as a veil, used to give dignity to the commencement of an Hellic sovereignty, which, in the person of Perseus, partly succeeded, partly supplanted, the Danaid throne.
Danaus has been mentioned by Hesiod, the first among the later authorities. This poet states, that he relieved Argos from drought: an operation which harmonises well with the tradition that brings him from a country dependent on the irrigation of the Nile, as the conditions of cultivation there could not but lead at an early date to care in the management of water. He likewise calls Perseus by the name of Δαναίδης, and also terms him the son of Danae[634].
The only point of connection between the Danaids and the Argive or Argeian name is, that Prœtus, the last of the Danaids, reigns over Argeians. But this is at a period when the Perseid house, which was evidently Hellenic, has already become the first in rank among the Greek thrones, and has given, as is probable, the Argeian name to the people of Eastern Peloponnesus. The whole evidence, therefore, throws the Danaan name, with all its incidents, back to a period anterior to that of Argeians and of Achæans.
But if the Danai were thus before the Ἀργεῖοι and before the Ἀχαιοὶ, whom did they follow?
Post-Homeric tradition.
The evidence of Æschylus in the Supplices supports the tradition which makes them immediately follow the Pelasgi[635], or which, more strictly, represents their name as the first of those borne by the Greek nation after it had ceased to be simply Pelasgic.
