The tertia poena (third punishment) referred to in Epigram 12 on page 42 is irrumation or coition with the mouth. The patient (fellator or sucker) provokes the orgasm by the manipulation of his (or her) lips and tongue on the agent's member. Galienus calls it lesbiari (Greek lesbiázein), as the Lesbian women were supposed to have been the introducers of this practice. Lampridius says: 'Libidinosus, ore quoque pollutus et constupratus fuit' (That lecherous man, whose mouth even is defiled and dishonest) and Minutius Felix: 'Qui medios viros lambunt, libidinoso ore inguinibus inhaerescunt' (They who lick men's middles, cleave to their inguina with lustful mouth).
In old Latin it was called offendere buccam, to offend the cheek. Suetonius calls the vice illudere ori--to sport with the mouth. Ausonius says that the Campanians were addicted to the practice, and calls it capitalis luxus--the debauchery of the head.[1] Arnobius uses the expression stuprum oris--the defilement of the mouth. Other terms used are: to corrupt the mouth; to attack the head; to defy to one's face; not to spare the head; to split the mouth; to gain the heights; to strike higher; to compress the tongue; complacently lending the mouth; the labour of the mouth; to lick men's middles; to lick and to make silent. Suetonius relates that Parrhasius bequeathed to Tiberius a picture which he had painted, representing Atalanta kneeling before Meleager
