A mantelletta, Italian diminutive of Latin mantellum 'mantle', is a sleeveless, knee-length, vest-like garment, open in front, with slits instead of sleeves on the sides, fastened at the neck. It was for a period of time even more common than the mozzetta. History The mantelletta is probably connected with the mantellum of the cardinals in the "Ordo" of Gregory X (1271–1276) and with the mantellum of the prelates in the "Ordo" of Petrus Amelius (d. 1401), which was a vestment similar to a scapular. Before 1969, it was worn instead of the mozzetta over the rochet by any bishop outside his place of jurisdiction. A symbol of prelacy, but also of limitation, it was therefore always worn by auxiliary bishops (who were never in their own dioceses), by an archbishop only when outside of his province, and by a bishop only when outside of his diocese. Within their own areas of jurisdiction they wore the mozzetta instead. The mantelletta was also worn by cardinals (who wore it under the mozzetta) only when in the city of Rome, as a symbol of the cardinal's rank throughout the church (hence they wore only the mozzetta even outside their own dioceses), but in deference to the pope's authority when in his home diocese (thus the only place where they wore the mantelletta). It was likewise ordinary choir dress for several classes of monsignor, the so-called prelates di manteletta: the protonotaries apostolic de numero (the highest class of monsignor), domestic prelates (now called "prelates of honor") who are also addressed as "monsignor," and others who had been granted the privilege to wear it, including auditors of the Sacred Roman Rota and a few other high functionaries of the Vatican if they were not bishops. Certain chapters of canons have also been specifically granted the privilege. The colour for cardinals was ordinarily red, in penitential seasons and for times of mourning it was violet, on Gaudete and Laetare Sundays rose-colour; for the other dignitaries, the same distinctions being made, the colour was violet or black with a violet border. Cardinals and bishops belonging to orders which have a distinctive dress, also abbots who are entitled to wear the mantelletta, retain for it the colour of the habit of the order (gray for Franciscans, black for Dominicans, white for Cistercians, etc.). The vestment was made of silk only when it is worn by cardinals or by
