Book excerpt: This study of the social content of the only Spanish epic surviving in more or less complete form provides a means of assessing the motives and intentions of the protagonist and of other characters. Chapters are devoted to such themes as the significance of kinship and lineage; amity as a system of fictive kinship, personal honor, and public organization; the importance of women and the meaning and function of marriage, dowry, and related practices; the emergence of polity as the result of a rivalry of social, legal, and economic systems; and the implications, within an essentially kin-ordered world, of the poem's notions of shame, honor, status, and social inequality.
