Fyodor Dostoyevsky, Crime and Punishment
, part 3, chapter 1 (tr. Constance Garnett):
Although Pulcheria Alexandrovna was forty-three, her face still retained traces of her former beauty; she looked much younger than her age, indeed, which is almost always the case with women who retain serenity of spirit, sensitiveness and pure sincere warmth of heart to old age. We may add in parenthesis that to preserve all this is the only means of retaining beauty to old age. Her hair had begun to grow grey and thin, there had long been little crow's foot wrinkles round her eyes, her cheeks were hollow and sunken from anxiety and grief, and yet it was a handsome face.
