Abstract
In a fast historical travel, the author reveals the transformations in religious manuscripts —written in Latin— since the time of Dominican friar San Vicente Ferrer until the first vernacular language prints, with the invention of the press. With exhortations of moral or doctrinal character, lives of saints, exempla (examples), religious lectures in the form of homilies or sermons (homiletic genre), usually referred to the Evangelium, preachers in those medieval times left us, thanks to the reportatores (scriveners) both laic and religious, sacred literature from which we can find examples in the Reserved Fund of the Mexican National Library.
