I read somewhere that two Genoese (maybe they were brothers) tried sailing west from Europe in 1291 and were never heard of again. Did their ship sink? Were they eaten by cannibals? Did they find some paradise-like island in the West Indies and decide to stay there instead of returning to Genoa?

If they landed on one of the islands likely to be passed on the way into the Caribbean, they might have indeed been captured by cannibals. I think the island GUadalupe was mentioned with that kind of culture in the 1421 book.
