Ferdinand von Spanien
Painted in 1638 or 1639, this version is now in the Prado and was completed shortly before his death while he was ill with gout. It was commissioned by Philip IV of Spain's brother Cardinal-Infante Ferdinand of Austria and on Ferdinand's death moved to the Spanish royal collection. In 1788 Charles III of Spain decided it was immodest and ordered it to be burned, but he died before that order could be carried out.
