head. It shows the same imperfections already remarked when dealing with the portrait of Philip IV in ordinary dress, of the Prado Museum. The painter must always find difficult the realisation of a portrait when the model belongs to a very high class of society, and whose occupations, duties and life, are so very different from those of the artist himself; especially in the case of Velasquez, who was a real slave a naturalism, and who always required models sharing with him the work of a successful achievement. It was not possible to demand this of a King, and more especially in those days of Frapa, when his whole attention was concentrated on the army besieging Lerida.
