Burne-Jones first planned a painting called 'The Hours' in the mid-1860s, but it was not until 1882 that he completed the picture now in Sheffield City Art Gallery, his second attempt at the idea. The painting shows six seated women related to one another by the colour of their gowns, which encompass the gradations of daylight from dawn until dusk. The study of a sleeping head is for the sixth and last figure on the extreme right of the group. Tate Gallery label, September 2004
The fine head above is for the last Hour, representing evening rest.
