The holdings of the Kórnik Library include a small printed book by Walenty Schreck published by the Königsbergian printing house of Johann Daubmann in 1559. At the beginning of the book, there is a hand-written dedication from the author to Duke Albrecht Frederick, a son of Albrecht of Prussia (von Hohenzollern), and a versed poetic work. Since the volume was a gift to a juvenile duke (and indirectly to his father), it was bound in a masterly manner: in covers with rich, almost entirely gilded ornamentation and with gilded edges. The paper offers an analysis of this book-binding work, taking similar objects from Polish collections and information from relevant literature as a point of reference. This allowed a thesis that the object is a representative creation of the leading 16th century Königsbergian book-binder Kaspar Angler, in which he used several of his characteristic decorating tools (such as a roll with fi gures of cupids and putti, a roll with a cortège of a king and bishop, and 3 medallion plaques with Biblical scenes). Taking into account its high artistry and almost untouched condition, the work seems to be one of the most impressive objects of the 16th century European bookbinding industry in the collection of the Kórnik library. Its high historical value also results from its provenance – it originates from the ducal library in Königsberg.

The collections of the Kórnik Library of the Polish Academy of Sciences include a set of printed textes by Jan Seklucjan with a handwritten dedication to Albrecht Frederick, Duke of Prussia (†1618). Their binding is decorated with plaquettes with portraits of Albrecht von Brandenburg- Ansbach, Duke of Prussia (†1568) and his first wife Dorothea (†1547). The article analyses both compositions, providing the following conclusions: they were made in the Konigsberg circles of the so-called Formschneider between the end of the 1530s and the first half of the 1540s. Between the period in question and 1565, wooden plaquettes (blocks) with these portraits were kept by the Duke’s court bookbinder, Kaspar Angler. After his death they probably belonged to the workshop equipment of his pupil Wolff Artzt, although it is also possible that they were used by a local religious writer, bookseller and possibly also bookbinder – Jan Seklucjan. Both works are examples of adaptation in Konigsberg of a specific formula of Renaissance book binding decoration, being at the same time a bookplate, based on a rectangular portrait plaquette presented in the centre of the cover. Compositions of such works most often depended on the painted portraits – mainly from the workshop of Lucas Cranach the Elder. Both Konigsberg portraits, however, are marked by prolonged proportions, a landscape background, and the display of coats of arms at the bottom. This fact should be explained by the painting models that were probably related to paintings in Albrecht’s Konigsberg residence. It is impossible to decide definitely whether they were made by a painter employed at his court (e.g. Crispin Herrant), or imported. Nevertheless, they are an indirect testimony to the existence of a gallery of portraits in the Konigsberg Castle, which was created on a long-term basis and with passion by the Duke of Prussia.
