This chapter uses the concept of homosociality to discuss attitudes to, and representations of, relationships between men. Examining masculinities and masculine characters from each of the forty sagas of Icelanders, this chapter constitutes the first comprehensive study of masculinities in this genre. It investigates the interpersonal dynamics of masculinity in the sagas, thereby demonstrating how masculinity inflects homosocial relationships (and thus virtually all aspects of saga texts). By focusing on the actions of male characters, this chapter touches upon, elucidates, and articulates many facets of saga society, and the representation of men within it, which are generally taken for granted and consequently not usually formulated in saga scholarship. The conclusions drawn about the operation of homosociality in saga society are concurrently used to think through some of the implications that Old Norse material might hold for Eve Kosofsky Sedgwick’s model of homosociality.
