Thanks ColonelZ. i rarely trust the dates of the experts (but maybe that's just me). The top two walls are the style of the Pelasgians. They taught the Greeks how to build. Pelasgian sounds a lot like Peleg to me, son of Eber. Or maybe mythological Pallas who i equate with Palestine (just a phoenetic guess). Who knows, maybe they're the same.
But if Joktan is Yucatan, it's not such a far stretch. They would be brothers.
