The cope (known in Latin as pluviale 'rain coat' or cappa 'cape') is a liturgical vestment, a very long mantle or cloak, open in 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 clergy, and also by lay ministers in certain circumstances. If worn by a bishop, it is generally accompanied by a mitre. The clasp, which is often highly ornamented, is called a morse.
