An asterisk is a small, folding metal covering which keeps the veil and Aër from disturbing the particles of bread on the diskos. The asterisk is made of two strips of metal laid one on top of the other and joined in the center by a brad or screw. When the two pieces are turned perpendicular to each other it forms a cross. The ends of the metal pieces are bent down so that it makes a standing frame. Sometimes, in Greek Catholic usage, a small star will be suspended from the asterisk where the two strips of metal are joined. Among Orthodox, however, the asterisk itself is considered to be the star, so no addition to it is deemed necessary. As the asterisk is one of the sacred vessels, it is usually kept on the Prothesis, where the bread and wine are prepared for the Eucharist, and no one except the priest or deacon should touch it. Often when a chalice and diskos are made, an Asterisk, and a liturgical spoon, and spear will be made to match them.
Use
During the Liturgy of Preparation, after the priest has prepared the bread and the wine, he will cense the asterisk by holding it over the open censer. He then places it on the diskos as he says the words, And a star came and stood over the place where the young child was. During a Hierarchical Liturgy, just before the Great Entrance, the veils and asterisk will be removed and the bishop will make commemorations for the living and the dead, after which he will replace the asterisk and veils. After the Sursum Corda, the deacon will lift the asterisk up from the diskos, and strike the diskos with it on four sides, making the sign of the cross, while the priest raises his hands and says, "Singing the triumphant song, shouting, crying aloud, and saying:" at which the choir begins the Sanctus. The deacon kisses the asterisk, folds it, and lays it aside on the Antimension, as the priest begins the Prayer of the Anaphora. After the Communion of the Faithful, the veils, spear, spoon, and asterisk are placed on the diskos. The priest hands them to the deacon, who carries them back to the Prothesis.
Coptic Use
In the Coptic Orthodox and Coptic Catholic Churches, the asterisk "consists of two silver arched bands, held by a screw, crossed over each other into the shape of a cross, usually surmounted by a small cross". In Arabic it is referred to as the Dome and is believed to represent both Christ's tomb and the cave in which he was born. Either the asterisk itself or the cross above it also symbolises the Star of Bethlehem. For this reason, the whole item is sometimes simply called the Star.
In the Roman Rite, a special twelve-ray asterisk was used in Papal Masses, as a covering for the host on the paten, when it was brought to the Pope at his throne for his Communion. Unlike the Eastern asterisk, which has four rays, the Papal asterisk had twelve rays, each inscribed with the name of an Apostle. Its use has been recently revived by Pope Benedict XVI.
