The masque was a form of festive courtly entertainment that flourished in 16th- and early 17th-century Europe, though it was developed earlier in Italy, in forms including the intermedio (a public version of the masque was the pageant). A masque involved music and dancing, singing and acting, within an elaborate stage design, in which the architectural framing and costumes might be designed by a renowned architect, to present a deferential allegory flattering to the patron. Professional actors and musicians were hired for the speaking and singing parts. Often the masquers, who did not speak or sing, were courtiers: the English queen Anne of Denmark frequently danced with her ladies in masques between 1603 and 1611, and Henry VIII and Charles I of England performed in the masques at their courts. In the tradition of masque, Louis XIV of France danced in ballets at Versailles with music by Jean-Baptiste Lully.
The masque tradition developed from the elaborate pageants and courtly shows of ducal Burgundy in the late Middle Ages. Masques were typically a complimentary offering to the prince among his guests and might combine pastoral settings, mythological fable, and the dramatic elements of ethical debate. There would invariably be some political and social application of the allegory. Such pageants often celebrated a birth, marriage, change of ruler or a Royal Entry and invariably ended with a tableau of bliss and concord. Masque imagery tended to be drawn from Classical rather than Christian sources, and the artifice was part of the Grand dance. Masque thus lent itself to Mannerist treatment in the hands of master designers like Giulio Romano or Inigo Jones. The New Historians, in works like the essays of Bevington and Holbrook's The Politics of the Stuart Court Masque (1998), have pointed out the political subtext of masques. At times, the political subtext was not far to seek: The Triumph of Peace, put on with a large amount of parliament-raised money by Charles I, caused great offence to the Puritans. Catherine de' Medici's court festivals, often even more overtly political, were among the most spectacular entertainments of her day, although the "intermezzi" of the Medici court in Florence could rival them.
