In Russia the icon of Our Lady of the Sign is called "Znamenskaya".  The icon shows Mary, the Mother of God with her arms outstretched in an attitude of prayer.  This position of prayer is called Orans and the image of the Mother of God in this position is sometimes called the "Oranta".  In her breast is a circular medallion with the Christ child blessing the world.  The icon originated in Byzantium and was considered a talisman of the Imperial throne there and in Russia.
