George IV (1762-1830), when Prince of Wales

George IV when Prince of Wales from 1791 by George Stubbs is a royal equestrian portrait of the future king, who was then twenty-nine and one of Stubbs's most important patrons. The prince commissioned multiple works from Stubbs in the late 1780s and early 1790s, including the celebrated Soldiers of the 10th Light Dragoons, and his patronage represented the highest social recognition available to an English artist. Stubbs's anatomical precision—founded on the eighteen months he spent dissecting horses before publishing his Anatomy of the Horse in 1766—gave him an authority that satisfied even the prince's obsessive attention to equine detail. The equestrian portrait places the prince on horseback in a landscape, combining formal regal presentation with Stubbs's characteristic precision in rendering both human and equine anatomy. The work is held at the Royal Collection.
