(Caligæ).
Ceremonial stockings of silk, sometimes interwoven with gold threads, and even heavily embroidered, worn by the celebrant of a pontifical Mass. Originally worn by priests, they were reserved about the eighth century for the exclusive use of bishops, a privilege recently extended to lesser prelates. In colour they correspond to the chasuble, but are never worn with black.
