_Aristophanes_ says in the _Frogs_, 1361-63: “Do you dare to criticize my songs, you that modulate your cadences on the twelve-fold postures of Cyrené?” Her name occurs also in the _Thesmophoriazusae_ (104), but merely her name. (Our invariable rule is to quote from Burmann’s edition of Aristophanes.) I am doubtful as to whether Musaeus should be counted among writers on the Erotic postures. Martial, XII., 97 recommends Instantius Rufus to read his (Musaeus’) books, as being of the most advanced lasciviousness, vying with those of the Sybarites in obscenity and full of the most suggestive and spicy wit; warning him at the same time to have his girl ready to hand, if he did not want his hands to perform the wedding-march and consummate the marriage without a woman at all. Footnote 9: _Athenaeus_, XIV., 13: “Also the Ionic dialect has to show the poems of Sotades and the “Ionic” poems preceding his, those of Alexander the Aetolian, and Pyres of Miletus, and Alexis, and others of the same class. The last mentioned is known as the Cinaedologue. But in this _genre_ the most eminent writer is Sotades, of Maroneia, as is stated by Carystius of Pergamus in his work on Sotades, and by Apollonius, Sotades’ son, who also wrote a work on his father’s poems. “His end was a miserable one. Having assailed Ptolemy Philadelphus, king of Egypt, with witticisms too independent for the sensitive ears of princes, the king caused him to be enclosed in a leaden casket, and thrown into the sea.” Footnote 10: Who were these “maids of Didymus.” Nobody knows. Failing any more plausible supposition, it may very well be conjectured that among the four thousand works written according to Seneca (Letter LXXX.-VIII.) by the Grammarian Didymus, there was one on the postures of lascivious girls, worthy to be named side by side with the treatises of Elephantis. Undoubtedly a man who devoted himself to such subtile questions as whether Anacreon was more libertine than drunkard, whether Sappho was a public woman or not, was quite likely to discuss the Erotic postures.
