In an Orthodox church the Royal Door or ‘Beautiful Gate’ is the central gateway of the icon screen that shields the sanctuary from view. It is a symbolic reminder of the gates of Jerusalem through which Christ entered, and is only used by the emperor and senior clergy who carry the Eucharist through to the faithful. These panels are typical of the icon painting tradition of northern Russia in the late sixteenth century. An Annunciation scene (as seen here), is an invariable feature of Royal Doors. The figures in bishop regalia are the fourth-century theologians Basil the Great and John Chrysostom, authors of the Holy Liturgy.
