The Johannes Grusch Workshop is named for the priest responsible for copying one of its bibles in 1267. The shop first appeared on the scene during the late 1230s, and a group of 39 manuscripts has been identified. The workshop's oldest dated work is a missal made for Rouen Cathedral between 1235 and 1245. The style expressed by the Grusch artist consists of flat little figures with inked draperies of a fairly irregular sort. The bodies have white heads with small features, like the short-bearded chins of the men and pursed mouths. A large number of painters were apparently associated with this workshop, which changed its style considerably over its thirty-year period of activity. Its painting can be divided into early, middle, and late styles.
