But isn t there an ahu (platform) on Easter Island with stonework identical to that of the Inca of ancient Peru?
A. Actually, no. There are several examples of extremely fine stonework on the island (at Vinapu on the southwest coast, for example, and at Vai Mata on the north coast). Heyerdahl drew attention to the stonework at Vinapu and it is similar to its Incan counterpart but in appearance only; the Inca used solid blocks of stone, whereas the ahu in question on Easter Island is back-filled with rubble. More problematical is the fact that the earliest available date for Peruvian polygonal block masonry is after 1440 ce, while that for the comparable stonework on Easter Island is c. 1200 ce.
