Written in 1428 by the German Carthusian, Oswald de Corda, prior of the Grand Chartreuse, the Opus Pacis consisted of two parts. One dealt primarily with orthography and accent, where Oswald stated that his motive in creating these codification rules was to dispel the anxiety of his fellow Carthusians. Many members of the order were worried about the omission of single letters, not just phrases, words or syllables within copies of a given text (demonstrating the new concern for uniformity taken to an extreme). It is clear that his audience was composed of scribes, specifically those meticulous to "the verge of neurosis". He seeks to reinforce the importance of older statutes regarding manuscript production, such as the Carthusian statutes, and the way in which he seeks to correct them.
