Cardinal-Infante Ferdinand of Austria
His commissioned works were mostly history paintings, which included religious and mythological subjects, and hunt scenes. He painted portraits, especially of friends, and self-portraits, and in later life painted several landscapes. Rubens designed tapestries and prints, as well as his own house. He also oversaw the ephemeral decorations of the royal entry into Antwerp by the Cardinal-Infante Ferdinand of Austria in 1635. He wrote a book with illustrations of the palaces in Genoa, which was published in 1622 as "Palazzi di Genova". The book was influential in spreading the Genoese palace style in Northern Europe. Rubens was an avid art collector and had one of the largest collections of art and books in Antwerp. He was also an art dealer and is known to have sold an important number of art objects to George Villiers, 1st Duke of Buckingham.
