Sermones de tempore et de sanctis (Sermons for certain times and Saints’ days), by Albertus Magnus is an incunabulum, printed in Ulm, Germany in 1479, and is the oldest book belonging to the Supreme Council Library.
The word incunabulum refers to books that were printed, not handwritten, prior to 1501. The Gutenburg Bible (1455) is probably the best known example of an incunabulum.
