Bronzino's best known works comprise the aforementioned series of the duke and duchess, Cosimo and Eleonora, and figures of their court such as Bartolomeo Panciatichi and his wife Lucrezia. These paintings, especially those of the duchess, are known for their minute attention to the detail of her costume, which almost takes on a personality of its own in the image at right. Here the Duchess is pictured with her second son Giovanni, who died of malaria in 1562, along with his mother; however it is the sumptuous fabric of the dress that takes up more space on the canvas than either of the sitters. Indeed, the dress itself has been the object of some scholarly debate. The elaborate gown has been rumored to be so beloved by the duchess that she was ultimately buried in it; when this myth was debunked, others suggested that perhaps the garment never existed at all and Bronzino invented the entire thing, perhaps working only from a fabric swatch. In any case, this picture was reproduced over and over by Bronzino and his shop, becoming one of the most iconic images of the duchess. The version pictured here is in the Uffizi Gallery, and is one of the finest surviving examples.
