Henry James Sumner Maine,
Ancient Law
(1861)
“ Why should a conception of Kinship, so elastic as to include strangers brought into the family by adoption, be nevertheless so narrow as to shut out the descendants of a female member? To solve these questions, we must recur to the Patria Potestas. The foundation of Agnation is not the marriage of Father and Mother, but the authority of the Father. All persons are Agnatically connected together who are under the same Paternal Power, or who have been under it, or who might have been under it if their lineal ancestor had lived long enough to exercise his empire. ”
