Michelangelo’s marble bust of the Roman politician Marcus Junius Brutus is titled Brutus. He carved it around 1539–1540, and the sculpture is now displayed at the Bargello in Florence.
The bust emerged during a Renaissance revival of the classical portrait bust. Brutus—celebrated as an opponent of tyranny and associated with the assassination of Julius Caesar—carried strong political meaning in Florence after the defeat of its republic and the return of Medici rule.
The work was commissioned by the republican Donato Giannotti for Cardinal Niccolò Ridolfi. Its heroic treatment presents Brutus less as a neutral historical portrait than as an emblem of liberty. Scholars have debated its precise date and whether Michelangelo left parts unfinished, but its identity as Brutus is secure.
