La Provinciale
Mohun regularly acted leading and major roles, mostly villains. His interpretations of Iago and of the title role in Ben Jonson's "Volpone" were famous, and he brought a sinister edge to the part of Pinchwife in William Wycherley's "The Country Wife". Mohun repeatedly seconded Charles Hart's leads, playing Iago to Hart's Othello, and Cassius to Hart's Brutus.
