Comprised of a variety of Jesuit and Jesuit influenced texts, including early exercises, Jesuit rules, and unknown Jesuit texts. Work 5 contains 65 rules, as did the original Reglas comunes created in 1551. Work 10 contains 11 rules for Jesuit students, as does the Ratio studiorum (Munich, 1600), with textual variations. Works 15, 16 and 27 contain texts related to Monumenta Ignaciana, textus Vallsioletanus (Colegio de Ingleses, Ms. 898, ff. 19r-34r), with textual variations. Work 18 contains 24 exercises, untraced to any existing printed work, likely inspired by Ignatius' exercises and other Jesuit works. Work 30 contains 12 instructions, likely based in part on the works of Saint Bernard of Clairvaux. Work 37 comprises the beginning of the ninth treaty, Tratado de confusión, of San Francisco de Borja's Tratados espirituales (Alcalá de Henares, 1550). All other texts have not been traced.
