Historical person

Gaius Cassius Longinus

83 BCE–43 BCE

Gaius Cassius Longinus was a Roman senator and general who became one of the principal organisers of the conspiracy against Julius Caesar. After the assassination in 44 BC, he raised forces in the eastern provinces and joined Marcus Brutus against the triumvirs.

Cassius commanded one wing at the Battle of Philippi in 42 BC but, mistakenly believing that Brutus’s forces had also been defeated, ordered a freedman to kill him. Gaius Cassius Longinus was born in Ancient Rome and died in Philippi.

Peter Tonkin’s After the Ides treats Cassius as one of the principal Liberators hunted after Caesar’s murder, while Richard Foreman’s Augustus: Son of Caesar shows Brutus and Cassius building resistance in the east as Octavian begins converting Caesar’s inheritance into political power. Fiona Forsyth’s Blood and Shadows begins after Philippi, among survivors still living with the defeat and deaths of Cassius and Brutus. Alex Gough’s Caesar’s Avenger follows the Second Triumvirate’s campaign to destroy the assassins and their armies. Tonkin’s Death at Philippi brings Cassius into the decisive Macedonian campaign itself, where his command and death help determine the collapse of the republican cause.
