To paint a character from the Bible, for an old man, a beggar, or a shepherd, he would go to the public square and the drinking dens, where he would be mostlikely to meet such persons. And he would draw a type or an animal from observation a hundred times before turning to his picture to fix it there for all time. He is said to have brought home peasants from the market and got them drunk in order to draw them. At the same time he was looking for laws; while studying the facial traits, he recorded the transitions in the closing and opening of the eyelid, the wrinkling of the nose, the pouting of the lips, in laughing, sneezing, yawning, cramps, perspiration, weariness, hunger-always he looked for the cause behind the expression which he was painting.
