The Orthodox, Byzantine or Russian (Orthodox) Cross is a variation of the Christian cross, commonly found in Eastern Orthodox Churches. The cross has three horizontal crossbeams—the top represents the plate inscribed with INRI, and the bottom, a footrest. In the Russian Orthodox tradition, the lower beam is slanted: the side to Christ's right is usually higher. In the Greek and some other Orthodox Churches, the footrest remains straight, as in earlier representations.
Russian variations 
A variation is a monastic "Calvary Cross", in which the cross is situated atop the hill of Calvary, its slopes symbolized by steps. To the viewer's left is the Holy Lance, with which Jesus was wounded in his side, and to the right, a cane with a wine-saturated sponge. Under Calvary are Adam's skull and bones; the right-arm bone is usually above the left one, and believers fold their arms across their chests in this way during Orthodox communion. Around the cross are abbreviations in Church Slavonic. This type of cross is usually embroidered on a schema-monk's robe.
Between 1577–1625, the Russian Orthodox Cross was depicted between the heads of a double-headed eagle in the coat of arms of Russia. It was drawn on military banners until the end of the 17th century.
