The Book of Kells (Dublin, Trinity College Library, MS 58, less widely known as the Book of Columba) is an ornately illustrated manuscript, produced by Celtic monks around AD 800 in the style known as Insular art. It is one of the more lavishly illuminated manuscripts to survive from the Middle Ages and has been described as the zenith of Western calligraphy and illumination. It contains the four gospels of the Bible in Latin, along with prefatory and explanatory matter decorated with numerous colourful illustrations and illuminations. Today it is on permanent display at the Trinity College Library in Dublin, Ireland.
