Hudibras.
Said to be a caricature of Sir Samuel Luke, a patron of Samuel Butler. The GrubStreet Journal (1731) maintains it was Colonel Rolle, of Devonshire, with whom the poet lodged for some time, and adds that the name is derived from Hugh de Bras, the patron saint of the county. He represents the Presbyterian party, and his squire the Independents.
