A few years back the book 1421 created a bit of a controversy in that it suggested the Chinese had discovered North America before Columbus. While people were arguing over the book’s details, others asked a simple question. Is it so hard to believe that an advanced empire with established seafaring skills couldn’t end up in the Americas? Many came out and supported the theory with their own evidences. It was almost like a taboo subject that scholars secretly pondered until 1421 changed things. Still, most don’t think it’s a slam-dunk case for Chinese visitors. Is it simply the resistance to new ideas? Or is the evidence not strong enough? In either case, another fascinating book on the subject is The Island of Seven Cities. It puts forth the case for a Chinese settlement in Canada. Perhaps there was.
