battle of the Tegeate with the Hyllean as an ancient tradition. But in the arrangement, by which it was contrived that the expeditions of the Heraclidæ should not be placed during the Trojan war and the youth of Orestes, we do not hesitate to suspect the industry of ancient systematic mythologists. 7. When the Heraclidæ had been once separated from the Dorians as belonging to a different race, and Hyllus set down as only the adopted son of the Doric king, it immediately became a matter of doubt at what time the junction of the Dorians and Heraclidæ in one expedition should be fixed. Sometimes the Dorians are represented as joining the Heraclidæ before the first, sometimes before the second, sometimes before the third expedition; by one writer as setting out from Hestiæotis, and by another from Parnassus.(211) There were doubtless no real traditional grounds for any one report; and still less any sufficient to place the name Hyllus, and the events connected with it, at any fixed epoch. Hence also Hyllus is at one time called the contemporary of Atreus, and at another of Orestes;(212) Pamphylus and Dymas are stated to have lived from the time of Hercules to the conquest of Peloponnesus.(213) Nor is there any absurdity in this, inasmuch as they are the collective names of races which existed throughout this whole period. The descendants of Hyllus, however, are no longer races, but, as it appears, real persons; viz., his son Cleodæus,(214) and his grandson Aristomachus. These names stood at the head of the genealogy of the Heraclidæ; as, for example, of the kings of Sparta; and they can hardly have been mere creations of fancy. From their succession is probably calculated the celebrated epoch of the expedition of the Heraclidæ, viz., 80 years after the Trojan war, which was without doubt determined by the early historians, since Thucydides was acquainted with it. The Alexandrine critics generally adopted it, as we know expressly of Eratosthenes, Crates, and Apollodorus.(215) But all that is recounted of the expeditions of these two princes, however small in amount,(216) cannot have been acknowledged by those who, like Herodotus, and probably all the early writers, stated the armistice after the death of Hyllus as lasting 100 years.(217)
