In the East as the West the vestment is specially associated with the ritual of the Eucharist.
The word mutzen, to dock, cut off, which first appears in the 14th century, does not help much, though the name of another vestment akin to the almuce - the mozzetta - has been by some traced to it through the Ital.
It is not in the East so specifically a eucharistic vestment as in the West, but is worn at other solemn functions besides the liturgy, e.g.
In the Armenian and Coptic rites the vestment is often elaborately embroidered; in the other rites the only ornament is a cross high in the middle of the back, save in the case of bishops of the Orthodox Church, whose sticharia are ornamented with two vertical red stripes (7rorayof, " rivers").
By the 16th century the almuce had become definitely established as the distinctive choir vestment of canons; but it had ceased to have any practical use, and was often only carried over the left arm as a symbol of office.
