This one Is in three parts.
1. Is it plausible that the Portuguese explored parts of the New World decades before Columbus survived his expedition in 1492?
2. If so what would be the earliest date Europe might be made aware of it?
3. Had the Vivaldi brothers made a one-way trip to the New World in 1292 or so what impact might that have on the native populations especially if they had two centuries to recover afterwards before more Europeans arrive?
