(1910–1991), born in County Donegal, Ireland, Simms, sometime Anglican archbishop of Armagh, wrote and lectured extensively on early Irish Christian manuscripts. His expertise on the Book of Kells is widely regarded. Simms's scholarship is accessible to younger readers in three children's books. The Book of Kells (1988) is an account of the creation of one of Ireland's great treasures; Brendan the Navigator (1989) tells the story of a monk who crossed the Atlantic in a coracle, and St. Patrick (1991) is the story of the man credited with bringing Christianity to Ireland.
