One of the angels parting the curtain. We should note that from the first drawing to the second and from the second to the third, but even more from the third to the fourth, Botticelli's drawings increasingly take on a totally separate language. One has the distinct feeling that the first and second drawings are still preliminary drawings, but from the third and fourth on, they become art unto themselves. One of the very important parts of Botticelli's contribution to his century is to have, so to speak, given the drawings nobility as a means of plastic expression. And he was, moreover, one of the first to have given drawings away.
