Klobuk

A klobuk is an item of monastic clothing worn by monks and, in the Russian tradition, also by nuns, in the Byzantine Rite, composed of a kamilavka (stiffened round black headcovering) with an epanokamelavkion, a veil which completely covers the kamilavka and hangs down over the shoulders and back.

Tonsured monastics always wear a klobuk in church and the refectory and whenever else formally dressed.

During the services, there are specified times when monks are to remove the klobuk and lay it on their left shoulder to denote reverence for the sacred , e.g., when the deacon brings the chalice out through the holy doors for Holy Communion.

[note 3] In the Russian tradition Archbishops and Metropolitans usually wear a small jewelled cross on the front of their klobuk as a mark of their rank.

The patriarchs of Moscow and Georgia wear an archaic form of klobuk that is rounded on top, and the former's is white, embroidered, and surmounted with a cross.
