H. Schurtz, Altersklassen und Männerbünde, 1902, p. 190. In this work Schurtz brings together (pp. 189-201) some examples of the germs of prostitution among primitive peoples. Many facts and references are given by Westermarck (History of Human Marriage, pp. 66 et seq., and Origin and Development of the Moral Ideas, vol. ii, pp. 441 et seq.).
Bachofen (more especially in his Mutterrecht and Sage von Tanaquil) argued that even religious prostitution sprang from the resistance of primitive instincts to the individualization of love. Cf. Robertson Smith, Religion of Semites, second edition, p. 59.
