Diego de Landa
Use and knowledge of the Maya script continued until the 16th century Spanish conquest at least. Bishop Diego de Landa Calderón of the Catholic Archdiocese of Yucatán prohibited the use of the written language, effectively ending the Mesoamerican tradition of literacy in the native script. He worked with the Spanish colonizers to destroy the bulk of Mayan texts as part of his efforts to convert the locals to Christianity and away from what he perceived as pagan idolatry. Later he described the use of hieroglyphic writing in the religious practices of Yucatecan Maya in his "Relación de las cosas de Yucatán".
