Perseus the founder of Mycenae (75 miles southwest of Athens) was the great grandfather of Hercules who lived in the days of Jason and the Argonauts circa 1300 b. c. and was one of the Argonauts for a short time. Perseus had sailed to North Africa to slay the Gorgon Medusa (probably an Amazon), and about a hundred years later, the Argonauts were blown off course into lake Tritonis (of northeastern Algeria) which had diminished and all but vanished by that time. The Greeks were well familiar with the western Mediterranean and eastern Atlantic, evidenced by the 12 Labors of Hercules, sailing over where Atlantis had been about two hundred years previously.
