History

The character of Arlecchino (Harlequin in English) originated in Bergamo, Italy, as a zanni (servant) character in the Commedia dell'arte. His costume was originally a simple peasant's outfit, but over time it evolved into the iconic diamond-patterned, multi-colored suit. He is typically portrayed as agile, acrobatic, and a trickster, often carrying a 'slapstick' (batocchio). The character spread throughout Europe, particularly influencing French pantomime and English harlequinade. The name 'Harlequin' itself is thought to derive from 'Hellequin,' a demonic figure in medieval French passion plays and folklore.

First Recorded Use

The character of Arlecchino emerged in Italy in the mid-16th century.

Cultural Associations

Harlequin is one of the most recognizable figures from the Commedia dell'arte, representing a blend of wit, physical comedy, and sometimes a touch of pathos. His distinctive costume has inspired fashion, art, and design, with the 'harlequin pattern' (diamond checks) being a common motif. In later adaptations, particularly in England, Harlequin became a magical figure, able to transform scenes with a touch of his bat. The character often represents the common person, using cunning to outsmart masters or rivals.
