Wibold (bishop of Cambrai)

[4] After the death of Bishop Ansbert, the leading men of Cambrai sent a letter to Emperor Otto the Great requesting the appointment of Wibold, which was granted.

[5] In the summer of 971, Wibold travelled to Italy for his investiture at Otto's hands, but the journey there and back caused his health to decline.

The cubical dice are made in the usual fashion with pips on opposite faces summing to seven, but in addition they are marked with the five vowels AEIOU in three different ways, so that each die is distinct.

The tetrahedral die is inscribed with four consonants on each face (BCDF, GHLK, MNPR and STXZ), so that a complete alphabet minus Q is present on the dice.

[2] There are 56 possible triples of dice to which Wibold assigned virtues, influenced by mystical approach to numbers that goes back to the Pythagoreans, especially Nicomachus of Gerasa, mediated by Christian authors.

They suggest that, if ever actually played, gameplay must have been broken into several sessions or else players were allowed to claim as all virtues covered by a given roll in a single turn.
