Marcus Antonius

Marcus Antonius (14 January 83 BCE - 1 August 30 BCE) was a Roman politician and general. A supporter and loyal friend of Gaius Julius Caesar, he formed a political alliance with Octavian after Caesar's assassination.

Alongside Octavian, Antonius led a military campaign to take down the Liberators, the forty Assassin Senators who played a part in the assassination of Julius Caesar. A civil war followed, with the armies of Marcus Junius Brutus and Gaius Cassius Longinus facing those of Antonius and Octavian. In 42 BCE, the two sides clashed at the in. Ultimately, Brutus and Cassius both took their lives in the face of defeat and the Roman Republic stood victorious.

Out of respect for Brutus, Antonius sent his most expensive purple mantle to Brutus' comrades for his body to be wrapped in it. The Assassins initially tried wrapping the body in the Shroud of Eden in an attempt to revive him, but were only momentarily successful. The Assassins stopped their attempt, and Brutus' corpse was then wrapped in Antonius' mantle.
