Born in the stagnant areas of lower Bergamo, quite the opposite of his compatriot Brighella,he shows little intellect, he is stupid, greedy and credulous. Harlequin is always dressed as a humble servant or a porter as in Carlo Goldoni’s "Servant to two Masters". The Harlequin costume consists of a jacket and trousers made of irregularly-shaped colored material, a white felt cap occasionally with a wooden spatula hanging from it. He wears a black half-mask with demonic features (legend is that the name Harlequin derives from a demon called Alichino cited by Dante Alighieri in Inferno, part of the "Divine Comedy").He sometimes has a bristly moustache and eyebrows and a large nose. A typical part of the Harlequin costume is the red lump on the head. It is an acrobatic mask with complex expressiveness.
His Bergamo accent is similar to Brighella but enriched with slang sayings and other dialectical expressions.

Brighella Cavicchio da Val Brembana is the long name for Brighella.
It’s the mask of an astute ingenious slave who knows how to help, but also how to dupe his master .
He is unscrupulous and can adapt to do any jobs.
He can be a host ,a soldier, a servant or an out-and-out thief.
He is the crafty servant in the commedia dell’arte. This mask has its origins in upper Bergamo and it is distinguished from its stupid and roguish counterpart from lower Bergamo.
The costume consists of a coat and large cloth trausers with a jacket with green stripes along the chest and stomach looking vaguely like plumage. Sometimes there is a short cloak over the shirt and a curious hat.
His speech is Bergamo dialect but with a particular accentuation making it sounds witty. He is an expert musician and singer and often carries a guitar.

Colombina is a malicious but charming servant-girl, a comical character, not always a mirror of virtue like her eternal suitor Harlequin. She is known not only as Colombine but also as Arlecchina, Corallina, Ricciolina, Camilla and Lisetta and later becoming the elegant Marionette in Carlo Goldoni’s "Crafty Widow". The costume is simple, similar to Harlequin’s with numerous multicolored patches. She wears a white cap, the same color of her apron. Sometimes, she looks like a servant girl from the 18th century and she is rarely seen wearing a mask. Colombine speaks Tuscan dialect but she doesn’t disdain other dialects.

This is the best-known of the Venetian masks. From it’s first appearance among the theatrical commedia dell’arte companies, Pantaloon "the Magnificent" spoke in unadulterated Venetian dialect. Pantaloon is an old merchant, often very rich and highly esteemed by the nobility, but sometimes a merchant in ruin (Pantalon dè Bisognosi). In either case he is still a very special old man because despite his age he is still capable of making amorous advances which never conclude in a positive way.He is a hard-nosed businessman, to the point of sacrificing the happiness of his sons and family harmony just so he can arrange some advantageous marriage.
The costume consists of a Greek woolen cap, a red jacket, scort belted breeches with a sword, or a hanky or a bag hanging from the belt. He wears a black cloak over his shoulders lined with red on the inside, black slippers or Turkish babouches with the ends pointing upwards. The mask reveals a large hooked nose, accentuated eyebrows and a curious goaty beard, which he usually strokes with his fingers. The Pantaloon costume is the most popular one during the carnival period. Pantaloon represents a commercial mind and a business acumen.
