Sparta's founding royal houses made a, uh, unlikely claim of being descended from Hercules, but regardless of the veracity of that, the Mycenaean Sparta of the Homeric cycle was destroyed by invaders (the excavation of the royal palace of that era has been going on for a few years now); other Mycenaean-era cities, as well as the giant levee at Gla, met a similar end. Interesting take on that, since the likely destroyers (under the revised chronology, rather than the conventional pseudochronology) would be the Scythians, or less possibly one of the other parties who destroyed Nineveh.
“(under the revised chronology, rather than the conventional pseudochronology)”
Does that mean everything I learned in school is wrong?
Since the Homeric period was at least 500 years before the Athens/Sparta competition, then perhaps those Spartans did indeed have Scythian or related influences.
