When she died in 2016, Dr Jennifer O'Reilly left behind a body of published and unpublished work in three areas of medieval studies: the iconography of the Gospel Books produced in early medieval Ireland and Anglo-Saxon England; the writings of Bede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, Adomnán 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 nine studies of the Insular Gospel Books. One of them, on the iconography of the St Gall Gospels (Essay 9), was left completed, but unpublished, on the author's death. It appears here for the first time. The remaining studies, published between 1987 and 2013, examine certain themes and motifs that inform the Gospel Books: their implicit Christology, their harmonisation of the four Gospel accounts, the depiction of Christ crucified, and the portrayal of St John the Evangelist. Two of the Books, the Durham Gospels and the Gospels of Mael Brigte, receive particular attention.
