The Indiculus superstitionum et paganiarum (Small index of superstitions and paganism) is a Latin collection of capitularies identifying and condemning superstitious and pagan beliefs found in the north of Gaul[1] and among the Saxons during the time of their subjugation and conversion by Charlemagne.
The manuscript is held in the Vatican Library in a collection (Codex Palatinus Latinus 577) which probably originates from Fulda and thence traveled to Mainz, arriving there in 1479.
Alain Dierkens argues, on the basis of word choice (the correspondence between the phrase superstitionem et paganiarum and the diction used by Boniface in his 742[2] letter to Pope Zachary) and a comparison between the content of the Indiculus and the conclusions of the Concilium Germanicum (744), that the Indiculus was indeed appended to or pertained to the decisions made at the Concilium Germanicum and the two consequent Frankish synods at Estinnes and Soissons.
[3] In other words, they were not the product of a late-seventh century scribe at Fulda, nor were the prohibitions aimed specifically or exclusively at the Saxons.
Since it is more or less contemporary with the activities of Saint Boniface in modern-day Germany, he has been called a "guiding influence" on its compilation.
