a daughter of the dictator L. Cornelius Sulla by his fourth wife, Caecilia Metella, and twin sister of Faustus Cornelius Sulla, was born not long before B. C. 88, the year in which Sulla obtained his first consulship ; and she and her brother received the names of Fausta and Faustus respectively, on account of the good fortune of their father. Fausta was first married to C. Memmius, and probably at a very early age, as her son, C. Memmius, was one of the nobles who supplicated the judges on behalf of Scaurus in B. C. 54. After being divorced by her first husband, she married, towards the latter end of B. C. 55, T. Annius Milo, and accompanied him on his journey to Lanuvium, when Clodius was murdered, B. C. 52. (Plut. Sull. 34; Cic. Att. 5.8; Ascon. in Scaur. p. 29, in Milon. p. 33, ed. Orelli.)

Fausta was infamous for her adulteries, and the historian Sallust is said to have been one of her paramours, and to have received a severe flogging from Milo, when he was detected on one occasion in the house of the latter in the disguise of a slave. (Gel. 17.18; Serv. ad Virg. Aen. 6.612.) The "Villius in Fausta Sullae gener" (Hor. Sat. 1.2. 64), who was another of her favourites, was probably the Sex. Villius who is mentioned by Cicero (Cic. Fam. 2.6.) as a friend of Milo; and the names of two more of her gallants are handed down by Macrobius (Saturn. 2.2) in a bon mot of her brother Faustus.
