Thanks, Frank!  I can see how a Prime Meridian crossing El Hierro somewhere (maybe its western tip?) makes a lot of sense (at least before that pest, Columbus )

Lu, you asked:
"Where is "Ferro Island" that you mention? "

That's the island "El Hierro" in the Canaries. There are good details in the Wikipedia article here: http://en.wikipedia.org/wiki/El_Hierro. It's the westernmost island in the Canaries, and as such it was the farthest point west known to classical geographers. Ptolemy himself supposedly (is this true?) was the first to suggest it, or whatever point should turn out to be actually farthest west in the Canaries, as the zero for longitude. It was a popular zero until the establishment of the Greenwich Observatory.
