Alea Evangelii is a game that was discussed in Corpus Christi College Manuscript 122, dated to the twelfth century CE and probably written at Bangor Abbey, Ireland. The document illustrates the board with pieces on it and provides an ecclesiastical explanation for the board with reference to the Christian Gospels. It seems to be a Christian justification for an earlier game, which appears to have been similar to other known tafl games. Modern scholars have suggested that the author of the manuscript may have made several errors in reconstructing the board and the placement of the pieces.
