A masquerade ball (or bal masqué) is an event which the participants attend in
costume, usually wearing a
mask. (A
masque is a formal written and sung court pageant.) Such gatherings, festivities of
Carnival, were paralleled from the fifteenth century by increasingly elaborate allegorical
Entries, pageants and triumphal processions celebrating marriages and other dynastic events of late medieval court life. Masquerade balls were extended into costumed public festivities in
Italy during the 15th century
Renaissance (Italian, maschera). They were generally elaborate dances held for members of the upper classes, and were particularly popular in
Venice. They have been associated with the tradition of the
Venetian Carnival.
