Book of Kells
The illuminated manuscript Book of Kells was probably at least begun at Iona, although not by Columba as legend has it, as it dates from about 800 (it may have been commissioned to mark the bicentennial of Columba's death in 597). Whether it was or not, Iona was certainly important in the formation of Insular art, which combined Mediterranean, Anglo-Saxon, Celtic and Pictish elements into a style of which the book of Kells is a late example.
