It was not until the second half of the 16th century that the first initiatives to found schools that covered more than religious indoctrination and reading and writing took place. The first bishop of Guatemala, Francisco Marroquín, requested the approval of the Spanish crown to set up a grammar class, in which Latin was to be taught, as it was the intellectual language of the time. This single fact has been the basis to perpetuate the myth that links bishop Marroquin to the early stages of the University of San Carlos.
