Julia (104 BC-after 39 BC) or Julia Antonia (known from the sources to distinguish her from other Juliae) was a daughter of Lucius Julius Caesar, the consul of 90 BC, and mother of the future triumvir and deputy of Caesar, Mark Antony. She was a sister of the Lucius Julius Caesar who was consul in 64 BC. Her mother is unknown. She was born and raised in Rome. Julia was a cousin of Julius Caesar.
Julia married Marcus Antonius Creticus, a man of a senatorial family. Their sons were the triumvir Mark Antony, Gaius Antonius and Lucius Antonius. Because of their kinship through her, Gaius Julius Caesar was obliged to promote the political careers of her sons, despite his distaste for their father and his generally low opinion of their abilities. After Julia’s first husband died in 74 BC, she married Publius Cornelius Lentulus (Sura), a politician who in 63 BC was involved in the Catilinarian conspiracy and was executed on the orders of Cicero.
Julia had raised her sons through her marriages. Plutarch describes her as one of “most nobly born and admirable women of her time”, though most other sources are considerably less flattering (and likely more accurate). The following clause from Plutarch describes her relationship with her first husband:
His father was Antony, surnamed of Crete, not very famous or distinguished in public life, but a worthy good man, and particularly remarkable for his liberality, as may appear from a single example. He was not very rich, and was for that reason checked in the exercise of his good nature by his wife. A friend that stood in need of money came to borrow of him. Money he had none, but he bade a servant bring him water in a silver basin, with which, when it was brought, he wetted his face, as if he meant to shave, and, sending away the servant upon another errand, gave his friend the basin, desiring him to turn it to his purpose. And when there was afterwards a great inquiry for it in the house, and his wife was in a very ill humour, and was going to put the servants one by one to the search, he acknowledged what he had done, and begged her pardon.
