The cappa of the Lateran basilica worn by the canons of Westminster cathedral, or the almuce worn, by concession of Pope Pius IX., by the members of the Sistine choir.
This, indeed, was its original meaning, the cappa having been an outer garment common to men and women whether clerical or lay (see Du Cange, Glossarium, s.v.).
Lastly, from the cappa is probably derived the mozzetta, a short cape with a miniature hood, fastened down the front with buttons.
At what date the cappa choralis developed into the cappa magna, a non-liturgical vestment peculiar to the pope, cardinals, bishops and certain privileged prelates, is not known; but mention of it is found as early as the 15th century.
The cappa choralis has already FIG.
The immantatio was the solemn investiture of the newo e immediately after his election b Papat means of the cappa rubea, with the papal powers.
The right to wear a violet cappa magna is conceded by the popes to the chapters of certain important cathedrals, but the train in this case is worn folded over the left arm or tied under it.
Besides the strictly liturgical vestments there are also numerous articles of costume worn at choir services, in processions, or on ceremonial occasions in everyday life, which have no sacral character; such are the almuce, the cappa and mozzetta (see Cope), the rochet (q.v.), the pileolus, a skullcap, worn also sometimes under mitre and tiara.
It is worn over the rochet by the pope, cardinals, bishops and prelates, the colours varying as in the case of the cappa magna.
From the hood of the cappa was developed the almuce.
