A Turk's head: Mr Henry Mossop in the guise of Bajazet from Nicholas Rose's play Tamerlane

The 1751 painting of a Turk's head depicting the actor Henry Mossop as Bajazet in Nicholas Rowe's play Tamerlane dates from Hogarth's later period, when his major satirical series were behind him and he was engaged in the theoretical investigations published as the Analysis of Beauty (1753). The theatrical subject reflects his lifelong engagement with the London stage and his interest in how theatrical performance — with its stylized costumes and exaggerated expressions — provided a laboratory for studying the grammar of human emotion and gesture. Mossop was a rising actor in the early 1750s, and his portrayal of Bajazet in Tamerlane — a play with political resonances, as Tamerlane represented William III and Bajazet stood for Louis XIV — would have appealed to Hogarth's interest in the intersection of theatre and politics. The character study bridges portrait and genre painting, using the theatrical costume and intense expression to create an image that is simultaneously a likeness and a study of dramatic passion. These theatrical character studies connect to the theory of expression that Hogarth was developing in his Analysis of Beauty, where he argued that the range of human faces and the Line of Beauty could be systematized into a theory of aesthetic judgment applicable to all the arts.

The character portrait captures theatrical intensity through Hogarth's bold handling and dramatic lighting, creating a study of expression that bridges portrait and genre painting.
