A half-face mask which covers the eyes and nose only, the domino (»lord«, from its origin as a nobleman's accessory for travelling incognito) is perhaps the quintessential masquerade mask, and also a stereotypical accoutrement of burglars. Conventionally black, they are, however, far more readily available in bright colors, motley, and any number of other kinds of decoration, sometimes to the point of entirely overwhelming the mask itself.

While these masks have a very weak anonymizing effect, they are nevertheless highly popular, likely the most popular Carnival mask, because of how convenient they are: leaving the entire lower face uncovered means that breathing, eating and drinking may be done perfectly unobstructed. Vain women also prefer them because the mask reveals the face and they prioritize showing off their looks over anonymity; a preference documented from at least the 18th century.
