Folios 1v-6r of the Book of Kells contain concordances or Canon Tables, drawn up by Eusebius of Caesarea (c.260- c.340), of Gospel passages which describe the same events in two or more of the Gospels. Displayed in tables under architectural arches (apart from canons IX – X which are placed in grids), these allowed the reader, at least in theory, to navigate from one Gospel to another.
Folios 2v-3r consist of Canon II, listing passages occurring in three Gospels: Matthew, Mark and Luke.
