A horrid mask, symbolising these memories, in bad dreams, grimaces beside her left hand.

The eyes of the mask are cut double so that the thing alters its glance as you move about the chapel, fascinates and is intolerable.

The noble and splendid thighs of the woman again realise a favourite problem of Michael Angelo's.

He represented these powerful limbs in the Flood and other parts of the Sistine vault, and in the Leda.

Beneath is seen an owl; never before in sculpture has a bird been represented with such power and dignity, save only by the Greeks in the eaglets head on the coin of Eiis.
