Coviello

Coviello (French: Covielle) is a minor character in the Commedia dell'arte. He falls into the category of the zanni. His name is a double diminutive of the name Giacomo (Jacob or James). In English, he might be called Jimmy or Jackie.

The character dates back to at least the 16th century. He was typically from the southern part of Italy, and could apparently dance and play the mandolin quite well.
