"From the Cnidian he takes only the head....He will allow the arrangement of the hair, the forehead, and the fair line of the brows to remain as Praxiteles made them; and in the eyes also, that gaze so liquid, and at the same time so clear and winsome--that too shall be retained as Praxiteles conceived it."
Lucian, Imagines (VI)
Of the many copies of the Praxitelean Aphrodite, the Kaufmann head in the Louvre is considered to be the most accurate.
