a friend of Cicero (Cic. Fam. 6.19), and probably the same person with Pompeius Macula mentioned by Macrobius in connection with a pun founded on his cognomen. Fausta, daughter of Sulla, the dictator [FAUSTA CORNELIA], had at the same time two lovers -- Fulvius, a fuller's son, and Pompeius Macula. Faustus, the lady's brother, remarked that, " he wondered his sister should have a stain (macula), since she had a fuller (fullo)" (Sat. 2.2.) The cognomen Macula is probably derived from some physical blemish.
