It is a name for Egyptians of the Christian faith and their Church. It is also the name for the last form of the ancient Egyptian language, which was written with mostly Greek letters. The Coptic language survives only as a liturgical language of the Coptic Orthodox Church.
The spherical silver cruet is a type of vessel made to hold wine or water for the Eucharist in the Coptic Mass.
It has a narrow mouth and a small base that probably contained a glass vessel. The deacon carries this flask in the offertory at the beginning of the liturgy. The priest takes it from the deacon and pours the wine into the chalice, which is placed on the altar in the sanctuary. After that, the priest proceeds with the service.
The cruet is decorated on the outer surface with small adjacent geometric circles that form clusters of grapes. This design is suitable for a cruet in which wine is kept.
