Heyerdahl's Peruvians must have availed themselves of that classical device of science fiction, the time machine, for they showed up off Easter Island in A.D. 380, led by a post-A.D. 750 lncan god-hero, with an A.D. 750 Tiahuanaco material culture featuring A.D. 750 lncan walls, and not one thing characteristic of the Tiahuanaco period in Peru and Bolivia. This is equivalent to saying that America was discovered in the last days of the Roman Empire by King Henry the Eighth, who brought the Ford Falcon to the benighted aborigines - Robert Suggs (1960a:224)
