Frontispiece from Illuminated Manuscripts in Classical and Mediaeval Times, their Art and their Technique. Painting on panel by a fifteenth century artist of the Prague school; it represents St Augustine as an Episcopal scribe. The background and the ornaments of the dress are stamped in delicate relief on the "gesso" ground and then gilt. This picture, which is now in the Vienna Gallery, was originally part of the painted wall-panelling in the Chapel of the Castle of Karlstein.
