«Drawing the human head was a hard-won skill that most artists practiced throughout their careers. In addition to mastering the face's physical aspects, artists confronted the more difficult tasks of mastering facial expressions and conveying personality. Leonardo da Vinci maintained that an artist's greatest challenge was to capture a person's moti mentali (motions of the mind). Since the Renaissance, artists have taken up this challenge to create effective characters and living presences in their narrative paintings and portraits.»
