A fine mezzotint portrait of Prince William Henry, Duke of Gloucester, engraved by Richard Earlom after Hugh Douglas Hamilton in 1771.

This mezzotint, produced by Richard Earlom in 1771, depicts Prince William Henry, Duke of Gloucester and Edinburgh. The work is based on an original portrait by Hugh Douglas Hamilton. Earlom was a master of the mezzotint process, a technique that allows for subtle gradations of tone and soft transitions between light and shadow. This specific print demonstrates his ability to render the textures of the Duke's formal attire and the delicate features of his profile with precision.

The composition is contained within a circular frame, a common device in eighteenth-century portraiture that directs the viewer's attention to the subject. The Duke is shown in profile, facing left, wearing a coat adorned with the star of the Order of the Garter. The background remains dark and atmospheric, which pushes the figure forward and creates a sense of depth. The lower margin contains the formal title and publication details, noting that it was printed for Robert Sayer at 53 Fleet Street, London.

Mezzotint was the preferred medium for reproducing oil paintings in the eighteenth century because it could replicate the painterly qualities of the original. Earlom's work here is clean and controlled, reflecting the formal requirements of royal portraiture during the Georgian era. The print provides a clear record of the Duke's appearance and status, capturing the refined aesthetic of the period. As a museum-grade reproduction, this print maintains the tonal depth and clarity of the original copperplate engraving, offering a window into the printmaking traditions of late eighteenth-century London.
