[2] The English poem in alliterative verse, commissioned by Humphrey de Bohun, 6th Earl of Hereford, was written c. 1350 by a poet named William.

[1]: 215  A single surviving manuscript of the English version is held at King's College, Cambridge.

Alfonso, who is Guillaume's cousin and a Spanish prince, has been changed into a wolf-shaped werewolf by his stepmother's enchantments.

He provides food and protection for the fugitives, and Guillaume eventually triumphs over Alfonso's father, and wins back from him his kingdom.

[1]: 218–19  The werewolf's protection of the child probably stems from the anecdote found in both The Seven Sages and Gesta Romanorum.
