Lucius Cassius Longinus (consul 30)

For other people named Lucius Cassius Longinus, see Lucius Cassius Longinus (disambiguation).

Lucius Cassius Longinus was a Roman senator, who was active during the reigns of Tiberius and Caligula. He was ordinary consul in the year AD 30 with Marcus Vinicius as his colleague.^[1] Longinus came from an ancient and noble gens, the Cassii. He is best known as the first husband of the Emperor Caligula's sister Julia Drusilla, whom he married in 33.^[2]

In early 37, he was appointed by Tiberius as a commissioner. After Caligula became Caesar later that year, he ordered Longinus to divorce Drusilla so that she could marry Marcus Aemilius Lepidus.^[3] While Longinus was proconsular governor of Asia (40/41), Caligula ordered his execution based on an oracle which Caligula interpreted as indicating that Cassius would assassinate him.^[4]
