Note 199 — Chapter V · —THE NATURE OF SEXUAL INVERSION.

Pedicatio (or pædicatio) is the most generally accepted technical term for the sodomitical intromission of the penis into the anus. It is usually derived from the Greek pais (boy), but some authorities have derived it from pedex or podex (anus). The terms "paiderastia" and "pederast" are sometimes used to indicate the same act and agent. This use, however, is undesirable. It is best to confine the word "paiderastia" to its proper use as the name of the special institution of Greek boy love. It may be added that the Greeks themselves had many names (as many as 74) for paiderastia. See, on this subject of nomenclature, Iwan Bloch, Der Ursprung der Syphilis, vol. ii, pp. 527, 563.
