In 1375 he wrote the patriotic poem *The Brus*, in couplets, on the Scottish war of independence and the deeds of King Robert and Douglas.
Similarities in meter and style to *The Brus*, as well as the inclusion of two Scottish saints, St. Machar and St. Ninian, seem to confirm for B. the attribution of the other poem *The Legend of the Saints*, drawn from the *Legenda Aurea*, which narrates the lives of 50 saints of the Western Church; and of another unknown work that expounds the events of the Gospel and the subsequent life of the Virgin Mary. Also controversial is his authorship of a book *The Legend of Troy*, of which two fragments remain, translated from Guido delle Colonne’s *Historia Destructionis Troiae*.
B. is a simple, natural writer, often detailed, but animated by sincere religious feeling and a spirit of freedom. He merits the distinction of having fixed the dialect of Northern England.
