There are two portraits fascinating to compare. The first is Ecce Homo by Philippe de Champaigne. It is also titled, "Christ Mocked," and, of course, is a depiction of the scene when our Lord is clothed in scarlet and given a reed and crown of thorns by the Roman soldiers. The second painting is Napoleon at Fontainebleau, 31 March 1814 by Paul Delaroche, depicting the emperor after his first abdication following the surrender of Paris to the Allies.
Both figures appear to be at their low-points. (Napoleon looks like me after a Bears game.) But there is a profound difference between the two. Napoleon is alone. Christ is not.
