Did an ancient mythological bird and son of a goddess really name Phoenicia? No, but then neither did a pair of mythological twins who suckled from the teat of their mother wolf found Rome.

Or did the mythological etymology come out of the name? In both of these ancient instances, we may, and probably will, never know.
