Exhibition of the week: Walk through British art
This major new hang of the permanent collection at the national gallery of British art promises a chronological overview of art in Britain since the Tudor age. It includes special displays on William Blake and Rose Wylie. Special attention is also being paid to Turner and Henry Moore. Will this, at last, be the killer rehang that finally makes Tate Britain an essential museum?

Masterpiece of the week

Good and evil, reason and madness are powerfully contrasted in this primal vision of Greek myth. The god Apollo, a glowing figure of virtue, destroys the monster serpent of chaos, Python. It marks a transition from primeval disorder to the reign of the gods. Turner's imagination sets this dawn of a new world against awe-inspiring natural powers that dramatise the profundity of Apollo's triumph.
