What is the dome?

The answer

The English “dome” is άσтης οι άσтξειοχος (astēs oi astexeiochos) in Greek. It is made 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. It reminds us of the tomb or of the star that appeared to the Magi. It was said that St. John Chrysostom introduced this article, which is placed on the paten to keep the holy bread, and to support the coverings.
