abstract:In this chapter I take up the reception of the Eusebian canon tables in the Hiberno-Latin exegetical tradition, since the Irish were exceptional in the degree of interest they demonstrated in Eusebius’ system, going well beyond the mere copying of the system in their gospelbooks. Indeed, Bernard Bischoff, in his seminal study inaugurating the study of Hiberno-Latin exegesis, highlighted an interest in the canon tables as a distinctive feature of this Irish tradition, but this observation has not received much elaboration in subsequent scholarship. Here I consider four representative texts which illustrate the way in which early medieval Irish scholars exploited the potential of the canon tables for understanding the gospels: 1) the poem Canon Evangeliorum of Ailerán of Clonard; 2) the Pauca de libris catholicorum scriptorum in euangelia excerpta; 3) the Irish Reference Bible; and 4) the commentaries of Sedulius Scottus. My argument is twofold. First, I suggest that these four texts are similar enough to one another that they form a distinct and identifiable tradition, belonging to the world of Hiberno-Latin biblical exegesis. Second, I argue that these texts demonstrate that their authors thought of the canon tables as more than merely ornamental decoration. Rather, they viewed them as an indispensable reading aid for understanding how the fourfold gospel, despite its diversity, nevertheless witnesses to the one Jesus. In this way, the Hiberno-Latin tradition, long noted for its magnificent artistic embellishment of gospelbooks, also stands out as unique within the broader Christian world for its focus on using Eusebius’ cross-referencing system as a hermeneutical tool for reading the gospels.
