Matthias Grunewald's painting of The Christ Resurrected (Isenheim Altarpiece).
This is my absolutely favorite icon image, Christ the Pantocrator from St. Catherine's Monastery, Mount Sinai. It is the oldest known icon of Christ, encaustic on panel. This is reported to be from the early 6th century and the lifelike qualities and realism of the expression are amazing.
