DID THEY MEET DOGMEN IN AMERICA?

Chinese records mention a ship from Fukien that sailed into the eastern Pacific in 507 AD.  The sailors discovered an island where Dog-Faced Men lived.  We do not have any more details.

That a continental mass could be mistaken for an island requires no stretch of the imagination and, if you sail far enough into the eastern Pacific, you'll strike the western coast of America.  One wonders how accurate this tale is.  My source is R. Fritze Legend and Lore of the Americas Before Columbus (1993).
