I was in the Victoria Maritime Museum today, having another look at Trekka and Tilikum, when I spotted a reference in an exhibit's caption to "Canada's Chinese Columbus". I spent some time tracking this down, and found this:
"Hwui Shan, an Afghan Buddhist priest who sailed with four Chinese monks on the "Great Eastern Sea" in A.D. 458, and returned to China an old man in the year 499 after a long voyage to Alaska and down the coast to Mexico. A look at the map indicates the route they recorded was not all that difficult: north east from China to Japan's most northerly island, further on the same course along the Kurile Islands to Kamchatka -- aided by the powerful Japanese Current and prevailing winds all the way. From there, they proceeded up the Aleutian Islands and following them to Alaska.
Hwui Shan gave a full report on the people, their dress, laws, customs, and industry. His description of the flora and fauna of the southern lands he called "Fu Sang" could only indicate Mexico. His writings describe a people who had carts hauled by horses, cattle, and deer, upsetting earlier theories (still held out as true) that the Original People of the Americas did not know the wheel. Archaeological finds in Mexico are of obvious Oriental influence, including a figure of Buddha.
On both sides of the Pacific, jade beads were placed in the mouth of the dead, and jade amulets were painted red cinnabar. There are sky-dragon motifs on Aztec temples. Whether they represent Asian influence in Mexico or Mexican influence in Asia is still to be determined. A number of archaeological finds in British Columbia indicate early visitors from Asia.
Hwui Shan's description of the culture of the Original Peoples was similar to that of Columbus'. "The people of the land are of a merry nature, and rejoice when they have an abundance. . . Travelling visitors do not prepare food for their journeys, and they have the shelter of the (inhabitants' dwellings. They have no fortifications or walled cities." He expressed surprise that the people did not have military weapons, nor waged wars."
I believe it comes from a Canadian magazine, "The Beaver", Spring 1983 issue. I've left a message for the librarian of the Museum to see if a copy is in their files. In the meantime, can anyone tell me if this article is referred to elsewhere? "1421", for example?
