The Lindisfarne Gospels are thought to be by Eadfrith, a monk who became Bishop of Lindisfarne in 698 and died in 721. The Gospels are richly illustrated, and were originally in a fine leather binding covered with jewels and metals. During the Viking raids on Lindisfarne, this cover was lost, and a replacement was made in 1852. The text is written in a hand known as 'insular script'.
