Once and for all (?) : Previous to 1492, discoveries of new lands were deeply hidden trade/national secrets. The official version of history claims there' no "proof" of this. But it isn't looking very hard for it, either.
Case in point : the ear of corn (maize) carved into Roslyn Chapel in Scotland.
Now there's another one (above) : a sketch of a kangaroo in a book compiled previous to the supposed "discovery" of Australia by Europeans.
