Allan Ramsay’s full-length portrait of Richard Grenville (1711–79) is undoubtedly one of his finest works, and indeed one of the finest British portraits of the mid to late eighteenth century. The subject is represented in the robes of a Knight of the Garter (to which he had been appointed in 1760), and the commission offered Ramsay a magnificent opportunity to depict in sumptuous van Dyck style one of the wealthiest, most politically powerful, and, above all, most fashionable men in England.
