A visard (also spelled vizard) is an oval mask of black velvet, worn by travelling women in the 16th century to protect their skin from sunburn. It was not held to the head by a fastening, but rather the wearer would clasp a bead attached to the interior of the mask between their teeth. The fashion of the period for wealthy women was to keep their skin pale, because a tan suggested that the bearer worked outside and was hence poor.

In Venice, the visard developed into a design without a mouth hole, the moretta, and was gripped with a button between the teeth rather than a bead. The mask’s prevention of speech was deliberate, intended to heighten the mystery of a masked woman even further.
