Clement of Alexandria, Miscellanies 18.104.22.168-137.4 (=BNJ 253F1 Thrasyllos of Rhodes)
‘Let’s summarize the timeline of the Greeks beginning with Moses. From the birth of Moses to the Jews’ escape from Egypt there were eighty years and then Moses died forty years later. The Exodus occurred at the time of Inachus. It was 340 years from the wandering of Sothis that Moses left Egypt. The amount of time from the leadership of Moses and the time of Inachus to the flood of Deucalion—and here I mean the second flood—as well as the immolation of Phaethon (which occurred at the time of Krotôpos) has been counted as forty generations when three generations are included in a hundred year period.
From the flood to the burning of Ida, the discovery of iron, and the Idaian Daktyls, seventy three years passed, according to Thrasyllos. And from the burning of Ida to the rape of Ganymede, sixty-five years passed. Following that period to Perseus’ expedition—when Glaukos established the Isthmian games in honor of Melikertês, there were fifteen years.
There were thirty-four years between Perseus’ expedition and the founding of Troy. After that, the voyage of the Argo happened 64 years later. 32 years passed from that time to the Theseus and the Minotaur. After this there were 10 years before the expedition of the Seven Against Thebes, three years until the founding of the Olympic games by Herakles in honor of Pelops and another nine years until the Amazons’ attack on Athens and Theseus’ abduction of Helen. The apotheosis of Herakles occurred 11 years after that. Four years later was Alexander’s rape of Helen. Then there were 20 years before the destruction of Troy followed by 10 years until Aeneas’ arrival after the fall of Troy and the founding of Lavinium. This means there were eight years before the reign of Ascanius. There were 61 years after this before the arrival of the Herakleidai. From then to the first Olympiad by Iphitos is 338 years.
