Alea Evangelii: The Anglo-Saxon Gospel Tafl Game
You have an unfinished game.
Rules at a glance
- Every piece, king included, moves like a rook: any number of empty squares along a row or column.
- Capture a soldier by trapping it between two of your pieces along a row or column (custodian capture).
- The attackers make the first move.
- Armies: 48 attackers against 24 defenders plus the king.
- The defenders win when the king reaches any of the four corner squares.
- The attackers win by capturing the king: he must be surrounded on all four sides.
- The king is armed: he can act as one side of a capturing sandwich.

Alea Evangelii, “the game of the Gospels,” is the giant of the tafl family: a 19×19 board carrying 48 attackers against 24 defenders and a king. It survives in a single medieval manuscript that does something no other game document dares: it claims the board is a diagram of the four Gospels.
A board game smuggled into a Bible
The source is Oxford, Corpus Christi College MS 122, an Irish gospel book from the twelfth century, probably made at the monastery of Bangor in County Down. Alongside the Gospels itself, folio 5v carries a full-page diagram of a huge game board dotted with pieces, followed by pages of Latin explanation. The text claims the game was brought from the court of the English king Æthelstan (reigned 924 to 939), which would push the tradition back into the Anglo-Saxon tenth century, though a claim in a later manuscript is evidence to weigh, not fact to bank.
The explanation is where things get wonderful. The author isn’t teaching you to play; he’s arguing that the arrangement of the board encodes the canon tables, the traditional charts showing where the four Gospels agree and differ. Pieces stand for concordances. Geometry becomes theology. Whether the monks who wrote this ever pushed pieces around the board, or simply found a game diagram irresistible as allegory, is a question scholars still enjoy.
For game historians the diagram is gold regardless, because it shows piece positions on a tafl-shaped layout at enormous scale. The game is played on the intersections of the grid, the way Go is, rather than in the squares. No rules text survives (the monks cared about salvation, not capture mechanics), so playable Alea Evangelii applies standard tafl rules to the manuscript’s board and setup.
How Alea Evangelii differs from Copenhagen
Sheer scale transforms everything. Copenhagen’s 11×11 board is a town square; 19×19 is open country with weather. Armies this large take many moves just to make contact, so Alea Evangelii has something no other tafl variant really has: a true opening phase, where both sides develop structure before any fighting starts.
The reconstruction here follows the manuscript’s setup with the family’s shared mechanics: rook movement, sandwich captures, an corner escape for the king, and none of Copenhagen’s modern additions. The rules summary beside the board reports the exact implementation.
Expect long games. Where Brandubh finishes in minutes, Alea Evangelii can absorb an afternoon, and the attackers’ encirclement problem becomes almost logistical: a perimeter this long has many places to leak. Some players find that scale tedious. Others find it the most atmospheric game in the family, a proper siege rather than a skirmish.
Who Alea Evangelii suits
Patient players, Go players curious about tafl, and anyone hooked by the manuscript story. It rewards planning over reflexes and punishes short attention spans without mercy. It is emphatically not a first variant; learn the mechanics on a small board, then come here when you want the epic version.
The tafl games overview places it among its smaller relatives, the rules reference covers the shared mechanics, and the board itself waits on the homepage.
FAQ
What does Alea Evangelii mean?
Latin for “game of the Gospels” (alea meant a board game, originally a dice game). The name comes from the manuscript’s own framing, which treats the board layout as a religious diagram encoding the gospel canon tables rather than as mere entertainment, entertainment being a hard sell in a gospel book.
Was Alea Evangelii actually played?
Unknown, and genuinely debated. The manuscript presents an allegory, not a rulebook, and its board plan may copy a real game or idealize one. The tafl-like layout suggests the diagram’s maker knew a real game of this family at large scale. The playable version here is a modern reconstruction on the manuscript’s geometry.
Why is the board so much bigger than other tafl games?
Nobody recorded a reason. The manuscript’s claimed origin at Æthelstan’s court hints at a grand, prestigious form of the game, and the allegorical purpose needed enough points to map the canon tables. It’s also possible large-format tafl simply existed and this is our one surviving witness.
How long does a game take?
Plan for an hour at minimum, and comfortably more between careful players. The armies start far apart and the encirclement takes many moves to build or break. See how long hnefatafl takes for comparisons across all six variants on this site.
