PICK OF THE WEEK

Rachel Whiteread

First major retrospective for the self-styled "greatest living British sculptor". Plaster casts and jelly-coloured resin moulds of the oh-so- significant spaces lurking undetected beneath such everyday household objects as chairs, tables, baths and mortuary slabs. In fact, after this show, about the only gaping void Whiteread still has left to fill is the one between her ears.

The Tate Gallery, Liverpool (0151-709 3223)

Peter Blake

Pop go the old masters as the veteran trendy re-works classic canvases from the National Gallery collection. Tarzan meets Jane care of Michelangelo's David and Da Vinci's Mona Lisa, Montagna's Madonna of the Rocks becomes Blake's Madonna of Trafalgar Square. You know the sort of thing.

From Thursday, National Gallery, Trafalgar Square, London WC2 (0171-839 3321)

Robert Mapplethorpe

Everything you always wanted to know (but were afraid to ask) about penises, pistils and the fun that consenting adults can have with them in the privacy of their own darkrooms.

Hayward Gallery, Belvedere Road, South Bank, London SE1 (0171-960 4242)
