Note 654 — LIFE OF CATO.
George Long translation
The text of Plutarch says that Livius Drusus was the uncle of Cato's mother, but this is a mistake, and accordingly Xylander proposed to read θείο μὲν ὄντι πρὸς τῆς μητρός. But Sintenis supposes that Plutarch may have misunderstood the Roman expression "avunculus maternus." Cato's father had by his wife Livia a daughter Porcia, who married J. Domitius Ahenobarbus. Livia's second husband was Q. Servilius Cæpio, by whom she had a son Q. Servilius Cæpio, whom Plutarch calls Cato's brother, and two daughters, named Servilia, one of whom married M. Junius Brutus, the father of the Brutus who was one of Cæsar's assassins, and the other married L. Licinius Lucullus (Life of Lucullus. c. 38).
