I know of only one definite case of role doubling in early English drama, and it is a rather late example. In 1584 the Coventry Smiths guild was responsible for a segment of the city's newly composed play on the siege and destruction of Jerusalem. The surviving guild records show that several members were paid various amounts for playing two, three, or even four separate roles in the same pageant. Curiously enough, the same records indicate that the Smiths also practiced "role halving," that is to say, a single role was sometimes parcelled out among several actors. There are probably other examples buried deep in the REED volumes, but this is the only one that comes to mind. --Steve Wright WRIGHTS@CUAVAX
