OIL PAINTING: Portrait of Stefano IV Colonna, 1546
The painting is signed and dated on the base of the column, where the inscription reads, "STE. COUMNA II. IL BRO(N)ZI(NO) FLO. FAC. MDXLUI". The date of 1546 would lead one to place the painting at the period of Bronzino's Roman sojourn. Likewise, the influences of Sebastiano del Piombo and Michelangelo, evident in this portrait, point to Rome. Nevertheless, the prototype for the portrait type of the military commander can be found in Titian's portrait of Guidubaldo della Rovere in the Galleria Palatina (Palazzo Pitti) in Florence. Bronzino's Colonna assumes the same pose as the sitter in the 1530 della Rovere portrait. The hypothesis that Bronzino executed the painting in Florence was confirmed as fact in 1981.
