Dulaure, Des Divinités Génératrices, ch. xv; Lea, History of Sacerdotal Celibacy, 3d ed., vol. ii, p. 278; Kiernan, "Asceticism as an Auto-erotism," Alienist and Neurologist, Aug., 1911.
This is the opinion of Löwenfeld, Ueber die Sexuelle Konstitution, p. 43.
Thus, Dühren (Iwan Bloch) remarks (Der Marquis de Sade und Seine Zeit, 1901, p. 211): "It is well known that England is today the classic land of sexual flagellation." See the same author's Geschlechtsleben in England, vol. ii, ch. vi. In America it appears also to be common, and Kiernan mentions that in advertisements of Chicago "massage shops" there often appears the announcement: "Flagellation a Specialty." The reports of police inspectors in eighteenth century France show how common flagellation then was in Paris. It may be added that various men of distinguished intellectual ability of recent times and earlier are reported as addicted to passive flagellation; this was the case with Helvétius.
A full bibliography of flagellation would include many hundred items. The more important works on this subject, in connection with the sexual impulse, are enumerated by Eulenburg, in his Sadismus und Masochismus. An elaborate history of flagellation generally is now being written by Georg Collas, Geschichte des Flagellantismus, vol. i, 1912.
