This lecture treats the use of bodies and body parts as they relate to kinship and social systems in Old Norse heroic legend and myth. In various ways, body parts can be appropriated for cosmic purposes or forfeited for enhanced abilities. But if an intact body represents an intact kin group (as language such as "within the knees" for "kin" suggests), appropriation or forfeiture of body parts suggests loss of kin, and also flaws in social systems in which kinship plays a role. Indeed, body parts and kinship—especially kinstrife—relate in powerful metaphorical ways.
