Manuscript notebook comprised chiefly of one or more cycles of Spanish sermons and sermon notes, referenced by feast day and accompanied by Scriptural readings in Latin; as well as brief extracts from other devotional texts and other notes in Spanish--for example, concerning medicinal recipes (fol. 218v) and a contemporary inscription mentioning two Spanish officials "juan diaz de aguero procurador general de los yndios y licenciado gaspar de valdes labrador de los yndios" (fol. 220v). Written down and corrected in an unruled bound book over a period of years, probably in the 1590s by a Franciscan friar working in or near Tlatelolco and Puebla (specifically Tecali, Huexotzingo, and Tlaxcala), New Spain. The contents are partially indexed (fols. 1r-2v). Of particular interest are two Nahuatl texts written in another hand: (1) sermons in Nahuatl and Latin (fols. 44r-54v), the first of which is described in the manuscript as having been given in "Sanctiago delante" by several priests, principally the Franciscan Fray Gerónimo de Mendieta (1525-1604), who was at Tlatelolco in the 1590s; and (2) a Nahuatl version of Ausías Izquierdo Zebrero's Spanish religious drama concerning Holy Wednesday, with related texts (fols. 201r-215v).
