Ancient Voyagers - Scandinavians traded with Native Canadians - 1700 BC

global seaworthiness is not a recent innovation, neither is astro-navigation, if we're to believe the well-documented evidence in the following (old) video...  seriously interesting stuff. Three thousand years BEFORE the so-called first-European i.e. Christopher Columbus.

In fact, the ancient Norse pre-oggam language used in engravings found on a limestone slab in Ontario show EXACTLY when they were done by analysis of precessional dating of the symbols and images carved... names are named. I love this stuff.
