Cumaean Sibyl
There are still intense areas of shadow which throw the Cumaean Sibyl into relief. But it is more than relief; it is the three-dimensionality which art-lovers expect to see in the work of the man who sculpted Moses. Critics of the restoration claim that this was Michelangelo's aim and that many frescoes had brightly contrasting colours laid side-by-side that were then worked over "a secco" to achieve this effect and that this is what has been lost by a too-scrupulous cleaning.
