The Horne Book (Danish: Hornebogen) is an evangeliary from the 13th century kept in the National Museum of Denmark. It may have been made for the Benedictine monastery Bosjökloster in present-day Sweden. In 1656 it was donated to Horne Church, where it remained until 1818, when it was taken to the National Museum in Copenhagen. It is richly decorated; it contains several full-page miniatures and other decorative elements, and its front cover is richly decorated by rock crystals, enamel, gold, and a crucifix made of walrus ivory.
