This article examines a group of five surviving twelfth- and thirteenth-century wax seal impressions from the British Isles that depict a scene of an armed knight in combat with a lion. This seal motif has tenuously been linked with crusading in the past, and so this paper seeks to address the connections between the sigillants and crusade, as well as the significance of commemoration of crusade culture on medieval seals. It highlights numerous links between this specific design and crusading experiences, literature and allegory. This paper focuses on an aspect of the medieval memory of crusade and the means of displaying chivalric, crusading identities within literate culture (on charters and letters) and in personal adornment.
