Das Graduale von St. Katharinenthal ist neu auf e-codices.ch online (via Newsletter e-codices Nr. 28).
«This gradual contains one of the most important artworks of Gothic illumination in Switzerland. The gradual is from the Dominican Convent St. Katharinenthal in the Canton of Thurgau and was created in that same convent in 1312. The book used to contain about 150 ornate initials (among them 60 historiated initials), which also were created in the area of Lake Constance. Several initials were cut out and are today held in various locations. e-codices is planning a virtual reconstruction of the manuscript.»
