Who does not know this mask, with his patched outfit and witty tongue? The first Harlequin we hear of is Alberto Naselli, from Bergamo, in 1572.
Harlequin is a poor character, wearing a colorful patched costume, the patches probably remnants of richer costumes.
Anarchic kind of behavior, always hungry and with no money, in modern times he could have been a hippie.
He's hungry, always, but he has all the necessary wit and creativity to get along, survive, take his satisfactions on the world that is constantly abusing him.
