Portrait of Cardinal Ippolito de' Medici

Giorgio Vasari's 1558 Portrait of Cardinal Ippolito de' Medici executed in fresco in the Palazzo Vecchio belongs to the systematic visual programme through which Cosimo I de' Medici constructed a monumental celebration of his dynasty. Ippolito de' Medici (1511–1535) was a colorful figure — illegitimate son of Giuliano de' Medici, briefly considered for marriage to Catherine de' Medici, made cardinal at nineteen, and dead at twenty-four, reportedly poisoned. His portrayal in the Palazzo Vecchio fresco cycle served the dynastic purpose of incorporating even collateral and short-lived family members into the visual record of Medici greatness. Vasari was the orchestrator of the entire Palazzo Vecchio decorative programme, and portraits within fresco cycles allowed him to integrate individual likenesses into the larger historical and allegorical narratives he was constructing for Cosimo.

Executed in fresco, the cardinal's portrait required Vasari to work quickly on wet plaster while maintaining the likeness quality expected of a formal portrait. Fresco technique necessitates confident, unflinching application, and Vasari's long experience with large-scale decorative fresco schemes gave him the fluency to render convincing portraits within complex multi-figure compositions.
