Note 89 — Chapter I · THE PATRIARCHAL THEORY
Reading edition
Plutarch, Roman Questions, VI, tells us that "in early times the prohibition of marriage extended as far as the tie of blood; and, if this be received, it involves—since the gentiles considered themselves to be of the same blood—that there could not be marriage between persons of the same gens."—McLennan, op. cit., 206, 207.
