Harlequins are a type of character traditionally found in Commedia dell'arte, a form of Italian theater that originated in the 16th century. They are often depicted wearing a colorful, diamond-patterned costume and a mask, symbolizing their playful and mischievous nature. Harlequins typically serve as comic figures, engaging in clever tricks and humorous antics. In modern times, the term "Harlequin" can also refer to various adaptations in literature, theater, and popular culture. For example, the character has appeared in literature, film, and television, often embodying themes of love, deception, and the complexities of human relationships.
