Harlequin is one of the most recognizable and enduring figures of the Commedia dell'Arte, an improvised form of theater performed by masked actors that originated in the mid-16th century in northern Italy but soon spread to the streets and courts of Europe. Commedia dell'Arte troupes were especially popular at the French court, where their performances were enjoyed for nearly two centuries. These shows involved drama, comic skits, and acrobatic routines not necessarily linked to any one story. Stock characters were identified by specific masks, costumes, and accessories. Although these have changed little today, the personalities of the characters have evolved. Harlequin, for example, was originally an oafish but agile figure from the Italian region of Bergamo, whose poverty was symbolized by a costume of multicolored patches. By the late 18th century, he had developed into a quick-witted trickster. His diamond-patterned suit now referred to his physical agility and to his multifaceted nature, at once cunning and foolish, shrewd and absurd.
