Cossutia was a Roman woman who became engaged to Julius Caesar prior to his reaching adulthood. There has been debate among historians on whether the marriage actually occurred.
Cossutia appealed to Caesar,[2] although the Cossuti were not even novi homines.[3] She was recommended to Caesar by his father and it is believed that the future dictator of Rome married Cossutia after he began wearing the toga virilis.[4] Both families issued coins with her image and were inscribed with Uxor Caesaris.[5] No children sprang from this relation. In 84 BC, after his father's death, Caesar left Cossutia and married Cornelia, as that was more pragmatic than the earlier relation to Cossutia.[2] It is also possible that Caesar chose to leave her to marry Cornelia because he had been nominated as Flamen Dialis, a role which demanded marriage to a patrician via confarreatio.[6]
