cf. Etymologicum Magnum 487.49, where the second vowel is epsilon and the garment is equated with the kausia (kappa 1139).
The word is used for a cap worn by court officials, and for the hood which forms a part of the monastic habit. See Lampe s.v. It is derived from Latin camella, via Medieval Latin camel(l)aucium. On the camelaucum as precedessor to the papal mitre in the 9th-10th century, see the Catholic Encyclopedia s.v. Mitre (web address 1). See also kappa 1588, pi 1600, and sigma 594. In modern Greek the word becomes kalimavki.
