When she died in 2016, Dr Jennifer O'Reilly left behind a body of published and unpublished work in three areas of medieval studies: the iconography of the Gospel Books produced in early medieval Ireland and Anglo-Saxon England; the writings of Bede and his older Irish contemporary, Adomnan of Iona; and the early lives of Thomas Becket. In these three areas she explored the connections between historical texts, artistic images and biblical exegesis. This volume brings together seventeen essays, published between 1984 and 2013, on the interplay of texts and images in medieval art. Most focus on the manuscript art of early medieval Ireland and England. The first section includes four studies of the Codex Amiatinus, produced in Northumbria in the monastic community of Bede. The second section contains seven essays on the iconography and text of the Book of Kells. In the third section there are five studies of Anglo-Saxon Art, examined in the context of the Benedictine Reform. A concluding essay, on the medieval iconography of the two trees in Eden, traces the development of a motif from Late Antiquity to the end of the Middle Ages.
