Liber illuministarum

The Liber illuministarum is one of the largest extant late medieval collections of art technological instructions and recipes for book painting. It was gradually compiled between the end of the 15th and the beginning of 16th century in Tegernsee Abbey (Bavaria) by eight identifiable scribes, among them the Benedictine monastery's librarian Konrad Sartori (died 1531). Written on paper it was only bound and arranged into one volume in the 16th century. Having in the course of time lost several pages it extends over 231 folios and is since 1803 preserved as:
 * Bavarian State Library (Munich, Germany), Cgm 821
