Leonid Ouspensky and Vladimir Lossky. The Meaning of Icons. 1952, pp. 72–73, ill. (color), call it "Christ Pantocrator" and place it in the end of the 15th century; comment on the symbolism and translate the composite text inscribed in the open book, from John 7:24 and Matthew 7:2.
Vitale Manin. Letter. received March 8, 1977, identifies it as "Christ Pantocrator" and dates it probably in the 16th century; notes that the Saviour is enthroned by a glory (a red zhomboid), an oval (heavenly powers), and a quadrangle (symbol of earth)—he is thus the ruler of heaven and earth.
