In the eighteenth century, the rin-no-tama was known in France, sometimes as "pommes d'amour." Thus Bachaumont, in his Journal (under date July 31, 1773), refers to "a very extraordinary instrument of amorous mystery," brought by a traveler from India; he describes this "boule erotique" as the size of a pigeon's egg, covered with soft skin, and gilded. Cf. F. S. Krauss, Geschlechtsleben in Brauch und Sitte der Japaner, Leipzig, 1907.
It may be worth mentioning that the Salish Indians of British Columbia have a myth of an old woman having intercourse with young women, by means of a horn worn as a penis (Journal of the Anthropological Institute, July-Dec., 1904, p. 342).
