A prose text of the Twelve Profits of Tribulation (MS. Royal 17 B xvii) based on the Latin treatise, De Duodecim Utilitatibus Tribulationis ascribed to Peter of Blois, archdeacon of Bath (†ca. 1200), was included by Horstmann in his edition of the works of Richard Rolle. Miss Hope Allen in her study of Rolle's writings has since demonstrated that this treatise is wrongly assigned to him. Horstmann also printed the text of the Twelve Profits from MS. Rawlinson C.894, and listed several other manuscripts containing prose versions of this treatise, in both English and French.
