This illustration of the four gospel writers comes from the Book of Deer, the earliest surviving example of Gaelic literature from Scotland. The Book of Deer is an illuminated Christian text, similar to the Book of Kells. It is named after the monastery of Deer and contains portions of the Gospels of Matthew, Mark and Luke, a portion of an Office for the Visitation of the Sick, the complete text of the Gospel of John and the Apostles’ Creed.
