If you Google ["Immanuel Velikovsky" Oedipus], there's some really interesting information about Velikovsky's analysis of why the Oedipus myth came out of Egyptian lore. Faldage suggested I check it out, and I did. One salient point Velikovsky made was the appearance of the sphinx in Sophocles, a most decidedly un-Grecian monster and ultra-Egyptian one. Velikovsky also points out that the meeting of the three roads where Oedipus kills his father in the Sophocles tragedy would have been unusual in how roads were laid in Greece, but not unusual in roads meeting at an oasis as shown on ancient Egyptian maps. There's by far more fodder at the trough of Velikovsky if you have some time....
