As discussed in a previous post , canon tables were intended to be a functional component of a medieval Gospel manuscript.1 That is perhaps one reason for adding canon tables to an existing Gospel text, such as in the Book of Mulling. While the Mulling Gospels were likely copied in the eighth century, the canon tables are thought to have been inserted in a later period. Beyond their usefulness as a concordance, canon tables also demonstrated the harmony of the Evangelists’ texts.2 In some cases, the agreement was expressed with the decoration framing the tables.
The design of canon tables could vary from manuscript to manuscript. They could be quite plain, as seen in the Book of Mulling (fig. 1). The Mulling canons are simply columns of numbers separated by red vertical lines. Corresponding passages are listed in the same row and so the table resembles a modern spreadsheet.
