The oldest known surviving example of the icon of Christ Pantocrator was painted in encaustic on panel in the sixth or seventh century, and survived the period of destruction of images during the Iconoclastic disputes that twice racked the Eastern church, 726 to 787 and 814 to 842. It was preserved in Saint Catherine's Monastery, in the remote desert of the Sinai. The gessoed panel, finely painted using a wax medium on a wooden panel, had been coarsely overpainted around the face and hands at some time around the thirteenth century. When the overpainting was cleaned in 1962, the ancient image was revealed to be a very high-quality icon, probably produced in Constantinople.
