Plutarch's Life of Caesar traces his rise from a young noble marked for death by Sulla to his assassination as dictator for life, framing his ambition as both his genius and his ruin.
Plutarch's Caesar opens with the young Caesar under threat from Sulla, who cannot be persuaded to make him divorce his wife and instead confiscates her dowry, then follows his capture by pirates, his early legal and political ventures, and his climb through Roman offices funded by ruinous personal spending. The narrative gives full weight to his ten years of campaigning in Gaul, including the crossing of the Rhine, the two expeditions to Britain, and the siege of Alesia, before turning to the collapse of his political partnership with Pompey and the senate's demand that he disband his army.
The biography then moves through the civil war in careful stages: Caesar's crossing of the Rubicon after an agonized hesitation on its bank, the swift conquest of Italy without bloodshed, the Spanish and Greek campaigns, the pivotal battle of Pharsalus, and Pompey's flight to Egypt and murder there. Plutarch follows Caesar to Alexandria and his entanglement with Cleopatra, through the African campaign against Cato and the remaining Pompeians, and the Spanish campaign against Pompey's sons, before describing his unprecedented honors, his appointment as dictator for life, and the mounting resentment this provoked among the senatorial class.
The work matters historically because it is one of the fullest surviving continuous narratives of the fall of the Roman Republic, written from within a genre devoted to moral character rather than political theory, and because its climactic account of the conspiracy and assassination on the Ides of March, including the omens, the seer's warning, and the killing itself, shaped how later readers understood the birth of one-man rule at Rome and its cost.
“Cornelia, the daughter of Cinna who had held sole power, Sulla, once he had gained control, could persuade Caesar to give up neither by hopes nor by fears, and so he confiscated her dowry.”
— Caesar
“he reached the river marking the border between Cisalpine Gaul and the remainder of Italy — the Rubicon, as it is named — the nearer he drew to the peril and the more he weighed in his mind the enormity of the venture he was risking, the more a sober reckoning overtook him”
— Caesar
“This skin will wait for Brutus”
— Caesar
“Well, the Ides of March have come”
— Caesar
“For this reason Brutus too struck him once, in the groin.”
— Caesar
Plutarch does not give Caesar a single famous catchphrase at the Rubicon; instead he describes an extended, agonized deliberation on the riverbank, with Caesar halting his march, debating silently, and discussing the decision at length with friends including Asinius Pollio before finally crossing. The dramatic weight in this text falls on the hesitation itself rather than on a memorable quotation.
Plutarch describes Caesar surrounded by the conspirators inside the senate meeting place, struck from all sides so that every conspirator had to take part, with Brutus delivering a blow to the groin; some accounts say Caesar pulled his cloak over his head and stopped resisting once he saw Brutus among his attackers. The murder is said to have drenched the base of a statue of Pompey with blood.
A seer had warned Caesar to beware a great danger on the day the Romans call the Ides of March. On the day itself, Caesar greeted the seer and joked that the Ides had come, and the seer replied that they had come but not yet passed, a line Plutarch presents as narrowly and eerily accurate.
Plutarch argues that the civil wars did not arise simply from a personal falling-out between Caesar and Pompey, but from their earlier alliance with Crassus, which let the two men combine to bring down the aristocracy's power before eventually turning that concentrated power against each other.
Cleopatra enters the narrative after Caesar arrives in Alexandria pursuing Pompey, becoming entangled in the dynastic conflict between her and her brother; Plutarch reports differing views on whether Caesar's passion for her needlessly prolonged and endangered the Egyptian campaign, before he leaves her ruling as queen of Egypt.
Plutarch reports that Caesar showed what contemporaries called a wonderful humanity toward those captured after Pharsalus, a clemency that reportedly moved even Pompey to lament his own rash decision to fight, though Caesar's later leniency toward men like Brutus and Cassius did not prevent their turning against him.
After his civil wars ended, the senate, having bent to his fortune and treating his monarchy as a respite from years of civil strife, appointed him dictator for life, an honor Plutarch presents as the final step that made his assassination seem justified to the conspirators.
Beyond the seer's warning, Plutarch records a torch of heavenly fire seen over Caesar's camp before Pharsalus and, after the assassination, an apparition that visited Brutus at night identifying itself as his evil spirit and promising to meet him at Philippi, which Plutarch treats as a sign the murder displeased the gods.
