The Aztecs were a pretty bloody culture when it came to things like human sacrifice, but archeologists have determined that they had a very high level of scientific development in such things as astronomy, calendars, herbal medicines, and . . . what else? We'll never know! They left plenty of books or scrolls, but none of them survived. The clergy, who followed in Cortez's footsteps, burned them all. They were the works of heathens! So they obliterated an entire culture. Same with Pizarro and the Incas. One wonders what the world lost. . . .
