The compass!

That was his secret..

Columbus was one of the first seafarers to realize that the compass,
invented hundreds of years before the days of King Ferdinand and Queen
Isabella, was not a child's toy, as almost everyone believed at the
time.

Huh!?!? The compass was commonly used by Europeans for
navigation for at least 200 years before Columbus, and in China
for a couple hundred years before that - possibly longer.

Don't you ever get *anything* right, even by accident?
