Tiberius Claudius Nero, father of the emperor Tiberius, a descendant of the preceding. He served under Julius Caesar, and commanded the fleet which defeated that of Egypt at the Canopic mouth of the Nile (48 B. C). He was made pontifex in place of P. Cornelius Scipio. On the murder of Caesar he was so fearful of sharing his fate that he even proposed that his assassins should be rewarded. When the triumvirs quarrelled he fled to Perusia, where his eldest son Tiberius, the future emperor, was born; and when Perusia surrendered to Oc-tavius, he escaped with his wife and child to Neapolis, whence he passed over to Sicily to Sextus Pompeius. Meeting with a cool reception from Pompeius, he soon departed from Sicily for Achaia, where Mark Antony was then sojourning. On the reconciliation of Antony and Octavius he returned to Rome. His wife Livia was much younger than himself, and exceedingly beautiful. Octavius saw her, became deeply enamored of her, and demanded her surrender from her husband. Claudius durst not refuse, and gave up his wife as a father would his daughter, and, when the ceremony was over, sat down to the nuptial feast with as much outward unconcern as any ordinary guest.
He died soon after, leaving Octavius the guardian of his two sons.
