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

Schless, Howard. "Knight's Tale: 965-67, 1462-75; Theseus's Banner, Palamon's Mickey." 25 (1990): 80-84.
Legal history might explain the unfurling of Theseus's banner in the Knight's Tale as the kind of action medieval kings performed. Also, legal history records a situation analogous to Palamon's use of a drug to escape his prison.
