This entire class is descended from New Haven, Beinecke Rare Book and Manuscript Library, Ms. 442, and it is merely an A1 subtype. All of these different arrangements of the forgeries actually reflect two different traditions. A1 with the so-called Cluny subtype and the shorter A2 version are all closely related to one another; the A/B version, with its B- and C- class derivatives represents a fundamentally different 'edition' of the forgeries. The other major Pseudo-Isidorian project, the False Capitularies, survive in twenty-three medieval manuscripts. Editions Efforts to publish the forgeries have been unsuccessful, with the Hispana Gallica Augustodunensis never published. Although several editions of the Capitularia Benedicti Levitae exist, the most recent (Monumenta Germaniae Historica, Leges, folio II, 2, 1831) is scholastically inferior to the 1677 Étienne Baluze edition. The False Decretals and the Capitula Angilramni have been published twice, with the 1863 edition by Paul Hinschius criticized for his choice of manuscripts. Hinschius also printed the genuine and interpolated parts of the collection by reprinting older versions of Pseudo-Isidore's genuine sources, making that portion of his edition critically unusable. Historians must return to J. Merlin's 1525 edition, based on a single 13th-century manuscript and reprinted in volume 130 of Jacques Paul Migne's Patrologia Latina. Influence For 150 to 200 years, the forgeries were only moderately successful. Although a relatively-large number of ninth- or tenth-century manuscripts is known (about 100 more-or-less complete manuscripts of the False Decretals, dating from the ninth to the 16th century, have been preserved), the canonical collections took little notice of the False Decretals until the early 11th century. During that century, the situation changed rapidly under the impetus of the Gregorian reforms and the Investiture Controversy. Spurred by monastic reform movements and the efforts of some Holy Roman Emperors, a group of cardinals and a series of popes strove to cleanse the church of abuses and free the papacy from its imperial patronage (which had recently freed it from the influence of Roman nobles). The reformers' efforts soon conflicted with temporal power; the bishops of the Holy Roman Empire were crucial to the emperors' power, forming the backbone of their administrative structure. This mingling of spiritual and temporal power was wrong, according to the reformers; Saint Peter had condemned Simon Magus (the "Simon" of simony), who tried to buy spiritual power. The alleged letters, allegedly from some of the most venerable Roman bishops, demonstrated
