The Chaucer Review: An Indexed Bibliography (Vols. 1-30)

Wenzel, Siegfried. "Notes on the Parson's Tale." 16 (1982): 237-56.
Certain passages in the Parson's Tale are closely related to sermon texts on pride and penitence. The image of the Tree of Penance derives from the Compileison de Seinte Penance which incorporates parts of the Ancrene Riwle. For all of its borrowing from sermons, the Parson's Tale is not a sermon, but a handbook devoted to penitence.
