José del Castillo
Castillo made many attempts to become Royal Painter for the Spanish monarchy, but he was never successful. This was not due to a lack of talent, but rather because Castillo allied himself with the wrong nobleman. His patron, the Count of Floridablanca, feuded bitterly with the Count of Aranda. The Count of Aranda was favored by King Carlos III, and as a result, Ramón Bayeu (Aranda's favorite painter) became Royal Painter.
