Pre-Columbian Peruvian
I believe the answer is:
inca
'pre-columbian peruvian' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for inca that I've seen before include "Ancient Peruvian like Cain" , "South American (historical)" , "mountain dweller" , "Old Peruvian descended from Cain" , "Aged Peruvian" .)
