"It floats off to Byblos in some accounts, which would be a North-Easterly locale..."
-- Byblos is debateable. Certainly there is the Phoenecian Byblos, as in Philo of Byblos.

I am curious when this name came into existance though. KBN seems to be the old name. Terms like KBNT - khebenit, seems to refer to a boat that trades with KBN.

Astarte, a phoenecian goddess, has been linked to Isis... and may point to the Phoenecian Byblos (Note: KBN seems to still be referenced in the Armana Letters)

An alternative Byblos in Egypt may have existed. I think I've seen a reference to a "Babylon" within Egypt, mentioned by Newton. Bybline Heights is mentioned by Aeschylus. Byblos by Plutarch.

I think there was a city of Byblos that was near Buto in the Western Delta.
