The link you gave us Sir was wrong, it doesn't work, so yeah, thanks for that.
Here's what I've managed to get:
Commedia dell'Arte is a form of theatre characterised by masking 'types' which began in Italy in the 16th century and was responsible for the advent of the actress and improvised performances based on sketches and scenarios. The characters in Commedia represented fixed social types.
Stock characters:
Arlecchino: the most famous. He was an acrobat and a wit, childlike and amorous. He wore a cat-like mask and motley colored clothes and carried a bat or wooden sword.
Brighella: Arlecchino's crony, was more roguish and sophisticated, a cowardly villain who would do anything for money.
Il Capitano (The Captain): a caricature of the professional soldier - bold, swaggering and cowardly.
Il Dottore (The Doctor): a caricature of learning - pompous and fraudulent.
Pantalone: a caricature of the Venetian merchant, rich and retired, mean and miserly, with a young wife and adventurous daughter.
Pedrolino: was a white-faced, moon-struck dream and the forerunner of today's clown.
Pulcinella: was a dwarfish humpback with a crooked nose, the cruel bachelor who chased pretty girls. This character is often seen in Punch and Judy shows.
Scarranuccia: dressed in black and carrying a pointed sword, was the Robin Hood of his day.
Inamorato (The Lover): handsome and went by many names. He wore no mask and had to be eloquent in order to speak the love declamations.
Inamorata: was former's counterpart: Isabella Andreini was the most famous. She is headstrong, flirtatious and articulate. Typically depicted as Pantalone's daughter. Men constantly fall in love with her and she loves to tease them and is often a prima donna.
Columbina: Inamorata's servent and was the beloved of Harlequin. She is a comic servant playing the tricky slave type and wife of Pierrot. She was often the only functional intellect on stage.
La Ruffiana: was an old woman, either the mother or a village gossip, who thwarted the lovers.Cantarina and Ballerina: often took part in the comedy, but for the most part their job was to sing, dance or play music.
Done.
