Usavan tambien esta gente de ciertos carateres o letras con las quales escrivian en sus libros sus cosas antiguas, y sus sciencias, y con ellas, y figuras, y algunas señales en las figuras entendian sus cosas, y las davan a entender y enseñavan. Hallamosles grande numero de libros destas sus letras, y porque no tenian cosa en que no uviesse supersticion y falsedades del demonio se les quemamos todos, lo qual a maravilla sentian, y les dava pena.
These people also used certain characters, or letters, with which they wrote down in their books their ancient history and their learning. With these letters, and with pictures and certain signs in the pictures, they understood their own affairs, explained them to others, and taught them. We found a great number of books in these letters of theirs. Because there was nothing in them that was free of superstition and the devil's lies, we burned them all. They grieved over this deeply, and it caused them great pain.
