Was America truly unknown to the outside world until Christopher Columbus discovered it in 1492? If so, how do we account for an Egyptian temple accidentally unearthed in Tennessee in 1935?

These enigmas are a tiny fraction of the abundant physical proof for Old World visitors to our continent hundreds and thousands of years ago. This title explores the evidence of pre-Columbian visitors and colonies in ancient America.
