This video shows Dr. Stephane Rene drawing and painting a very large Pantocrator - the Blessing Christ. He is Coptic Orthodox and is an expert and proponent of the neo-Coptic style pioneered by Isaac Fanous. The medium is egg tempera of silicate ground but what is so interesting is how fluidly and easily he paints those perfect smooth parabolic lines! He blogs at copticonography.org
