Painting of Moravian spiritual leader Christian Renatus von Zinzendorf, 1727-1752. The words on the paper he is holding say "Gebrochne Augen," "Broken eyes," referring to the belief that by looking into Christian's eyes one was seeing the eyes of Christ at the moment of his death.
Perhaps Valentine Haidt.
