Sir Harry Wildair is a character from George Farquhar's play The Constant Couple.
Subject: Theatre.
The artist is probably the same James Smith who engraved portraits of the English King in 1733.
Under the design 2 columns of verse are inscribed: "To copy Nature by the nicest Rules, / Describe the Hero, or delineate Fools; / In ev'ry Character to charm the Age, / None WILKS excell'd that ever trod the Stage. / With graceful Ease through ev'ry Scene he shone, / And Nature blush'd to See her self outdone. / Sir Harry Wildair, when by him display'd / Each Nymph no longer wish to be a Maid. / Whom shall we find to act that taking Part, / With so much Freedom, still disguising Art! / Since on the Stage we WILKS no more must see, / Sir Harry now may trip to Jubilee".
