Aspasia

William Gaddis, The Recognitions, pp. 939:

As fashions have originated with courtesans throughout the ages, she soon became their arbiter. And since she was, like the better class of whores in ancient Greece, a trained entertainer, no more opprobrium attached to distinguished men visiting her than fell to Socrates visiting Aspasia, and even after she had ruined him, and found herself accused of impiety, the great man appeared at her trial as her advocate, only to find his eloquence to fail him in court: ‘he could only clasp Aspasia to his breast and weep.’

Aspasia (ca. 470 BC –ca. 400 BC) (Ἀσπασία) was a Milesian woman who was famous for her involvement with the Athenian statesman Pericles. Very little is known about the details of her life. She spent most of her adult life in Athens, and she may have influenced Pericles and Athenian politics. She is mentioned in the writings of Plato, Aristophanes, Xenophon, and other authors of the day.
