Smyrna Gaius Cassius Longinus came from a very old Roman family,
gens Cassia, which had been prominent in Rome since the 6th century BC. Little is known of his early life, apart from a story that he showed his dislike of despots while still at school, by quarreling with the son of the dictator
Sulla. He studied philosophy at
Rhodes under Archelaus of Rhodes and became fluent in
Greek. He was married to
Junia Tertia, who was the daughter of
Servilia and thus a half-sister of his co-conspirator
Brutus. They had one son, who was born in about 60 BC.
Carrhae and Syria In 54 BC, Cassius joined
Marcus Licinius Crassus in his eastern campaign against the
Parthian Empire as quaestor. In 53 BC, Crassus led the Roman army at the
Battle of Carrhae in Northern-
Mesopotamia, considered the worst defeat since the disastrous loss at Cannae in 216 BC against Hannibal. Cassius led the remaining troops' retreat back into Syria, and organised an effective defence force for the province. Plutarch’s account suggests Crassus could have avoided crushing defeat in Carrhae by listening to Cassius' advice not to invade Parthia. According to Dio, the Roman soldiers, as well as Crassus himself, were willing to give the overall command to Cassius after the initial disaster in the battle, which Cassius refused. The Parthians also considered Cassius as equal to Crassus in authority, and superior to him in ability. In 51 BC, Cassius was able to ambush and defeat an invading Parthian army under the command of prince
Pacorus and general Osaces. He first refused to do battle with the Parthians, keeping his army behind the walls of
Antioch (Syria's most important city) where he was besieged. When the Parthians gave up the siege and started to ravage the countryside, he followed them with his army harassing them as they went. The decisive encounter came on October 7 as the Parthians turned away from Antigonea. As they set about their return journey they were confronted by a detachment of Cassius's army, which faked a retreat and lured the Parthians into an ambush. The Parthians were suddenly surrounded by Cassius's main forces and defeated. Their general Osaces died from his wounds, and the rest of the Parthian army retreated back across the
Euphrates.
Civil war '' (1806) by
Vincenzo Camuccini Cassius returned to Rome in 50 BC, when
civil war was about to break out between
Julius Caesar and
Pompey. Cassius was elected
tribune of the plebs for 49 BC, and threw in his lot with the
Optimates, although his brother
Lucius Cassius supported Caesar. Cassius left Italy shortly after Caesar crossed the
Rubicon. He met Pompey in
Greece, and was appointed to command part of his fleet. In 48 BC, Cassius sailed his ships to
Sicily, where he attacked and burned a large part of Caesar's navy. He then proceeded to harass ships off the
Italian coast. News of Pompey's defeat at the
Battle of Pharsalus caused Cassius to head for the
Hellespont, with hopes of allying with the king of
Pontus,
Pharnaces II. Cassius was overtaken by Caesar en route, and was forced to surrender unconditionally. Caesar made Cassius a
legate, employing him in the
Alexandrian War against the very same Pharnaces whom Cassius had hoped to join after Pompey's defeat at Pharsalus. However, Cassius refused to join in the fight against
Cato and
Scipio in
Africa, choosing instead to retire to Rome. Cassius spent the next two years in office, and apparently tightened his friendship with
Cicero. In 44 BC, he became
praetor peregrinus with the promise of the
Syrian province for the ensuing year. The appointment of his junior and brother-in-law,
Marcus Brutus, as
praetor urbanus deeply offended him. Although Cassius was "the moving spirit" in the plot against Caesar, winning over the chief assassins to the cause of
tyrannicide, Brutus became their leader. On the
Ides of March, 44 BC, Cassius urged on his fellow liberators and struck Caesar in the chest. Though they succeeded in
assassinating Caesar, the celebration was short-lived, as
Mark Antony seized power and turned the public against them. In letters written during 44 BC, Cicero frequently complains that Rome was still subjected to tyranny, because the "Liberators" had failed to kill Antony. According to some accounts, Cassius had wanted to kill Antony at the same time as Caesar, but Brutus dissuaded him. , including a
denarius of Gaius Cassius Longinus (A), which was minted on campaign in Europe in 43 or 42 BC
Post-assassination Cassius's reputation in the East made it easy to amass an army from other governors in the area, and by 43 BC, he was ready to take on
Publius Cornelius Dolabella with 12
legions. By this point, the Senate had split with Antonius, and cast its lot with Cassius, confirming him as governor of the province. Dolabella attacked but was betrayed by his allies, leading him to commit
suicide. Cassius was now secure enough to march on
Egypt, but on the formation of the
Second Triumvirate, Brutus requested his assistance. Cassius quickly joined Brutus in
Smyrna with most of his army, leaving his nephew behind to govern Syria as well. The conspirators decided to attack the triumvirate's allies in
Asia. Cassius set upon and sacked
Rhodes in 43 BC, while Brutus did the same to
Lycia. They regrouped the following year in
Sardis, where their armies proclaimed them
imperator. They crossed the
Hellespont, marched through
Thrace, and encamped near
Philippi in
Macedon. Gaius Julius Caesar Octavian (later known as
Augustus) and Mark Antony soon arrived, and Cassius planned to starve them out through the use of their superior position in the country; however, they were forced into a pair of battles by Antony, collectively known as the
Battle of Philippi. Brutus was successful against Octavian, and took his camp. Cassius was defeated and overrun by Mark Antony. Unaware of Brutus's victory, he ordered his freeman Pindarus to help him kill himself. Pindarus fled afterwards and Cassius's head was found severed from his body. He was mourned by Brutus as "the Last of the Romans" and buried in
Thassos. ==Epicureanism==
