Mémoires, vol. i, Chapter VII.
Among leading English novelists Hardy shows an unusual but by no means predominant interest in the feet and shoes of his heroines; see, e.g., the observations of the cobbler in Under the Greenwood Tree, Chapter III. A chapter in Goethe's Wahlverwandtschaften (Part I, Chapter II) contains an episode involving the charm of the foot and the kissing of the beloved's shoe.
Schinz, "Philosophie des Conventions Sociales," Revue Philosophique, June, 1903, p. 626. Mirabeau mentions in his Erotika Biblion that modern Greek women sometimes use their feet to provoke orgasm in their lovers. I may add that simultaneous mutual masturbation by means of the feet is not unknown to-day, and I have been told by an English shoe-fetichist that he at one time was accustomed to practice this with a married lady (Brazilian)—she with slippers on and he without—who derived gratification equal to his own.
