able to adopt the personae of his characters in order to successfully portray them on stage. In lines 157–158, Euripides's unnamed relative retorts: "Well, let me know when you're writing satyr plays; I'll get behind you with my hard-on and show you how." This is the only extant reference to the genre of satyr plays from a work of ancient Greek comedy and, according to Shaw, it effectively characterizes satyr plays as "a genre of 'hard-ons.'" In spite of their bawdy behavior, however, satyrs were still revered as semi-divine beings and companions of the god Dionysus. They were thought to possess their own kind of wisdom that was useful to humans if they could be convinced to share it. In Plato's Symposium, Alcibiades praises Socrates by comparing him to the famous satyr Marsyas. He resembles him physically, since he is balding and has a snub-nose, but Alcibiades contends that he resembles him mentally as well, because he is "insulting and abusive", in possession of irresistible charm, "erotically inclined to beautiful people", and "acts as if he knows nothing". Alcibiades concludes that Socrates's role as a philosopher is similar to that of the paternal satyr Silenus, because, at first, his questions seem ridiculous and laughable, but, upon closer inspection, they are revealed to be filled with much wisdom. One story, mentioned by Herodotus in his Histories and in a fragment by Aristotle, recounts that King Midas once captured a silenus, who provided him with wise philosophical advice. Mythology According to classicist William Hansen, although satyrs were popular in classical art, they rarely appear in surviving mythological accounts. Different classical sources present conflicting accounts of satyrs' origins. According to a fragment from the Hesiodic Catalogue of Women, satyrs are sons of the five granddaughters of Phoroneus and therefore siblings of the Oreads and the Kouretes. The satyr Marsyas, however, is described by mythographers as the son of either Olympos or Oiagros. Hansen observes that "there may be more than one way to produce a satyr, as there is to produce a Cyclops or a centaur." The classical Greeks recognized that satyrs obviously could not self-reproduce since there were no female satyrs, but they seem to have been unsure whether satyrs were mortal or immortal. Rather than appearing en masse as in satyr-plays, when satyrs appear in myths it is usually in the form of a single, famous character. The comic playwright Melanippides
