In page Zanni:

"

The second Zanni is known as lo stupido. The second Zanni must be foolish, clumsy, and dull. The second Zanni is also unable to tell his right hand from his left. He is a dull-witted peasant who can be simple and also ridiculous.[3] Second Zanni, in particular with Harlequin, does not so much advance plot as maintain a steady stream of comic relief throughout the scenario.[4] Second Zanni are assumed to be from the lower city of Bergamo.[4] Between the two of them they make up one person of "less than average intelligence".[5] Before developing this dualistic person of the two types of clever and silly servant, Zanni was a character in its own right.[citation needed]
