Kalimavkion

A Kalimavkion (Greek: καλυμμαύχιον), kalymmavchi (καλυμαύχι), or, by metathesis of the word's internal syllables, kamilavka (Russian: камилавка), is an item of clerical clothing worn by Orthodox Christian and Eastern Catholic monks (in which case it is black) or awarded to clergy (in which case it may be red or purple).
