This reinterpretation of the Equestrian Portrait of Prince Balthasar Charles painted by Diego Velázquez in 1635 comes from the series Amusements in the Prado (Entretenimientos en el Prado) which Pablo Serrano created as an homage to the art by the Spanish grand masters. The sculptor from the Aragonese region of Crivillén regularly visited the Museo del Prado. Accordingly, in 1962, with all of the experience he had collected, he decided to create a series of revisions of pieces by Goya, Velázquez, Titian, and El Greco, devoting the volume to the most famous figures in Spanish art history. Among them is this equestrian portrait of Prince Balthasar Carlos, whose initial large-scale version was cast in 1962. Later, when he returned to the series in 1974, he created another edition of the same piece. It wouldn't be the only piece dedicated to this figure—he would also reinterpret Prince Balthasar Charles as a Hunter by Velázquez in the same year.
