Eusebius’ Canon Tables are well known. Lavishly decorated, they can be found in many medieval gospel books. Their purpose is to help finding parallels in the four gospels. However, it is less known the Eusebius also drew up a system of “canon tables” for the psalms. This system is much less sophisticated, but it may be an important pre-stage of the famous gospel synopsis. It is significant both for the early history of illuminated Christian books and for the history of exegesis.
