1819: Charles Willson Peale, on David Porter

(Entry in Peale's Diary)

Porter “thought that I had made it too handsome for him. I find that he is one of those characters who puzzle portrait painters who undertake to portray them. He is seldom a minute in the same position, for when anyone speaks he turns toward them and never thinks that it is necessary to keep himself in the same view to the painter. So that the painter, having formed his design, must watch to sketch the traits as quick as possible.”
