The calendar contains an alchemical, medieval recipe for gold from the "Collection of recipes for various arts" - Schedule diversarum artium, Theophilus Presbyter (ca. 1070-1125). The schedule allows for a detailed familiarization and analysis of the techniques of artistic crafts in the Middle Ages. The work is divided into three volumes. The first volume contains information on techniques, production and use of materials for drawing and painting, the use of paint and ink, especially for book painting and wall painting. The second volume concerns stained glass and stained glass technique. The third volume is devoted to goldsmithing and it is there that the oh-so-"practical" recipe for gold is given.
