Final answer:
Julia married Cornelius Lentulus after the death of Marcellus. Their marriage is mentioned by Plutarch and was significant to the political dynamics of the era, including the tensions between Mark Antony and Cicero.
Step-by-step explanation:
After Marcellus' death, Julia married Cornelius Lentulus, an event recorded by the Greek biographer Plutarch. This marriage occurred after her first husband's death, Antony. Cornelius Lentulus was involved in the conspiracy of Catiline and was eventually put to death by Cicero, which fueled the hatred between Mark Antony and Cicero.
Pompey, Julia's former husband, was seen as an emotional individual who married multiple times, often for political reasons. However, his marriage to Julia, the daughter of Julius Caesar, appears to have been genuine as they were reported to have deeply fallen in love. Their alliance through marriage was initially a political strategy to solidify the bond in the Triumvirate between Caesar and Pompey.
