This is the mask of Coviello, one of the lesser known Commedia characters, but fun to play.

Coviello was often depicted as a neighbor of Pantalone, lower status, but possible husband to Pantalone's daughter. Some say he was a servant (zanni) from Southern Italy, who, once freed, acted like a capitano. He was a complainer, but also sly, adroit, and conceited.

Physical Characteristics
Coviello moves more like a capitano (wide, grounded stance, large gestures) than a servant. He can be sly and slinky at times, and moves quickly when he needs to. He often uses confused language.

A comparable animal image for Coviello is a hyena.
