This portrait of Cosimo II de' Medici (1590-1621) can be dated, based on the sitter's apparent age, to early in the second decade of the 17th century. It appears to relate to Justus Suttermans' full-length portrait of the Grand Duke in the Uffizi, Florence, with some differences to the costume (see K. Langedijk, The Portraits of the Medici: 15th-18th Centuries, Florence, 1981, I, pp. 540-541, no. 31, fig. 28,31).
