Flagon
A flagon is a large leather, metal, glass, plastic or ceramic vessel, used for storing and pouring drink, whether this be water, ale, or another liquid. They are generally not intended to be drunk from directly, like a cup or tankard. A flagon is typically of about in volume, and it has either a handle, or one or two rings at the neck. Sometimes the neck has a large flange at the top rather than rings. The neck itself may or may not be formed into one, two or three spouts. The name comes from the same origin as the word "flask".
Christian use
As a Roman Catholic term of use, the flagon is the large vessel, usually glass and metal, that holds the wine. Before March 2002, a flagon may have also been used to hold the wine during the consecration of the Eucharist and then be poured into many chalices. This pouring of sacramental wine from flagon to chalice was eliminated. A smaller container called a cruet is used for the priest's chalice, usually identical to the cruet of water, which is mingled with the wine before consecration. The cruets do not remain on the altar after the preparation of the gifts.In the Anglican Church, the flagon is the vessel that contains the wine to be consecrated. If more than one chalice is used during the administration of Communion, the flagon is placed on the altar at the Offertory, and other chalices are brought to the altar after the Breaking of the Bread. There should be only one chalice on the altar during the Great Thanksgiving.
