Q. 1. What is the Mitre used for?
A. 1. The mitre is a kind of folding-cap. It consists of two like parts, each stiffened by a lining and rising to a peak; these are sewn together on the sides, but are united above by a piece of material that can fold together. Two lappets trimmed on the ends with fringe hang down from the back. The mitre is, theoretically, always supposed to be white.
The mitre, the common headdress of bishops, is worn at liturgical functions. It is either precious, golden (orphreyed), or simple (simplex). The precious mitre is worn by celebrants, the simple by concelebrants, and the golden by the celebrant at an ordination. All the cardinals wear a damasked mitre (simplex) in presence of the Pope. It is very tall, and is made of layered white damask silk.
