History Buff: I guess I'm a heretic for you and I don't know that stzory about the ship. Anyway, the story obviously isn't very popular as there is little material I could find in a "quick-search" on that topic. I know that scholars for long time were also very "conservative" in the Viking-thing, but when reasonable proofs were made historians didn't hide it. So I guess that finding "undenyable proof" would not go unnoted or undebated by the scientific community.
I'm not saying that Phoenicians could not possibly have gone to America, but as proof is poor and "exchange" between the Old World and the New, whether it be wild-life, plants or culture, didn't take place, the following options seem possible to me:
a) no phoenician set foot on America.
b)one or two "accidental landfalls", because of storm or because some "mad navigator" wanted to go further westwards even after he hadn't seen land for quite some time, took place but had no effect, neither on America nor on the Phoenicians.
If knowledge of land bexond the ocean would have become accessible to a people like the Phoenicians they would have established quite a bit trade...
I'm tending not to believe such stories easily because I know how many people want to have it that way, not because I deny the possibility of proof coming up in the future.
