Mantelletum

is a large cape of silk reaching from the neck to below the waist, with open spaces for the arms on each side. It is commonly worn over the rochet, and is no doubt the foreign equivalent to the English chimere. Anciently it was of scarlet satin in England. Foreign bishops commonly wear a mantelletum of purple silk, lined with silk of the same color, only lighter in shade. Abroad, in some places, monsignori, canons, vicars-general, apostolical prothonotaries, and doctors in canon law wear the mantelletum; in which case it is usually of black, though sometimes of scarlet or brown silk. The mantelletumn is by some affirmed to be the same as the mozette.
