I am scheduled to become a godfather for the first time in a few weeks, and I just purchased an icon for the baptismal name that my godson is taking (after John the Forerunner and Baptist). After purchasing this icon, I did a little research to track down its source, and I am recording this here to pass along. (First are the images. Below them is the information that I found regarding the source.)
This Deësis is from Dormition Cathedral in Moscow. Originally written in the first third of the 13th century. Vladimir-Suzdal in Russia. Tempera on wood. 61.5 cm by 146.5 cm. It was located in the Assumption Cathedral of the Moscow (Kremlin) on the southern wall, above the tomb of Metropolitan Philip. Restoration was begun in 1935 in the State Armory, continued and completed in 1936 in the State Tretyakov Gallery.
In Byzantine art, and later Eastern Orthodox art generally, the Deësis or Deisis (Greek: δέησις, “prayer” or “supplication”), is a traditional iconic representation of Christ in Majesty or Christ Pantocrator: enthroned, carrying a book, and flanked by the Virgin Mary and St. John the Baptist (and sometimes other saints and angels). Mary and John (and any other figures) are shown facing towards Christ with their hands raised in supplication on behalf of humanity.
