Clodius was a man of noble birth, young in years, but bold and presumptuous in spirit. This man, being in love with Pompeia, Caesar's wife, got into his house secretly, by assuming the dress and guise of a lute-player; for the women of Rome were celebrating in Caesar's house that mysterious rite which men were not allowed to witness,¹ and no man was there; [2] but being still a beardless youth Clodius hoped without being noticed to slip through to Pompeia along with the women. But since he got in at night and the house was large, he lost his way in the passages; and as he was wandering about, a maid of Aurelia, Caesar's mother, caught sight of him and asked him his name. Being thus compelled to speak, he said that he was looking for an attendant of Pompeia named Abra, whereupon the maid, perceiving that his voice was not that of a woman, raised a cry and called the women together. [3] These shut the doors, searched carefully all about, and found Clodius, who had taken refuge in the chamber of the girl with whom he came into the house. The affair having become noised abroad, Caesar divorced Pompeia and had an action for sacrilege brought against Clodius.
