   Roberto Delpiano's Carnival of Venice page offers information on the carnival tradition in Venice, Italy.  This site includes lots of information on Commedia and its characters, as well as other carnival traditions.

    To see examples of period Italian dress, you might want to visit The Costumer's Manifesto page of Renaissance clothing links.  This page has links to external as well as internal sites on Renaissance costume.  Here is a good place to see what kind of clothes all of the characters might wear, but you could most likely use this site for the Lovers and Capitano.
