Cope

A cope ( ("rain coat") or ("cape")) is a liturgical long mantle or cloak, open at the front and fastened at the breast with a band or clasp. It may be of any liturgical colour.

A cope may be worn by any rank of the Catholic or Anglican clergy, and by licensed lay ministers on certain occasions. If worn by a bishop, it is generally accompanied by a mitre. The clasp, which is often highly ornamented, is called a ''morse''. In art, angels are often shown wearing copes, especially in Early Netherlandish painting. Provided by Wikipedia
