Giancarlo de' Medici (1611-1663), Cardinal, at the age of 10.

Buonavita employs chiaroscuro to model the boy’s figure, allowing the vivid red garments and gold trim to emerge from the shadowed space. Fine brushwork renders the white ruffled collar, star‑patterned vest, and delicate stockings, while the controlled handling of light gives the portrait a three‑dimensional presence.

Created in Florence in 1622, the portrait entered the Habsburg imperial collections during the 18th century, eventually becoming part of the Kunsthistorisches Museum’s holdings. Documentation traces its movement from the Medici family archives to the Viennese gallery, where it has been conserved and exhibited as part of the museum’s Italian Baroque assemblage.
