Charles I can be compared to King Henry VIII and King George III as a highly influential royal collector; he was by far the keenest collector of art of all the Stuart kings. He saw painting as a way of promoting his elevated view of the monarchy. His collection reflected his aesthetic tastes, which contrasted with the systematic acquisition of a wide range of objects that was typical of contemporary German and Habsburg princes. By his death, he had amassed about 1,760 paintings, including works by Titian, Raphael and Correggio among others. Charles commissioned the ceiling of the Banqueting House, Whitehall from Rubens and paintings by artists from the Low Countries such as Gerard van Honthorst and Daniel Mytens. In 1628, he bought the collection that the Duke of Mantua was forced to sell. In 1632, the peripatetic king visited Spain, where he sat for a portrait by Diego Velázquez, although the picture is now lost.
