A fine mezzotint reproduction by Richard Earlom after Diego Velázquez, depicting the young Prince Balthazar Carlos on horseback.

This mezzotint by Richard Earlom reproduces the famous equestrian portrait of Prince Balthazar Carlos, originally painted by Diego Velázquez in 1635. Earlom, a master of the mezzotint technique, translates the tonal depth of the Spanish Baroque original into a monochromatic medium. The print captures the young prince in a dynamic pose, mounted upon a rearing horse, set against a sweeping view of the Sierra de Guadarrama.

Earlom employs a sophisticated range of greys and blacks to render the textures of the horse's coat, the prince's velvet attire, and the atmospheric quality of the sky. The mezzotint process involves roughening the copper plate to hold ink, which allows for the smooth transitions between light and shadow seen here. This method was particularly suited to replicating the painterly qualities of seventeenth-century oil works. The composition emphasises the prince's status through his confident posture and the dramatic scale of the animal, reflecting the courtly traditions of the Spanish Habsburgs.

As a printmaker, Earlom was highly regarded for his ability to interpret the works of old masters for a wider audience. This specific work demonstrates his technical precision in managing the subtle gradations required to mimic the luminosity of Velázquez's brushwork. The print serves as a record of the original painting, which resides in the Museo del Prado. It offers a glimpse into the eighteenth-century appreciation for European masterworks, where the art of the print allowed collectors to possess reproductions of works located in distant royal collections. The attention to detail in the landscape and the prince's regalia remains consistent with the high standards of British printmaking during the late eighteenth century.
