Exhibition of the Week
Agnes Martin
One of the greats, an abstract artist of minimalist rigour and ethereal craft whose vision is as pure as prairie rain.
• Tate Modern, London, 3 June until 11 October.
Other exhibitions this week
Duane Hanson
The eye-fooling sculptor of people so lifelike they make you doubt your own perceptions.
• Serpentine Gallery, London, 2 June until 13 September.
Julian Opie
Cool people reductively portrayed – is it glib pop art or a brilliant interpretion of the perceptual process?
• Alan Cristea Gallery, London, 5 June until 18 July.
Urs Fischer
One of the most interesting artists around reveals new provocations.
• The Modern Institute, Glasgow, 6 June until 29 August.
Alex Frost
Art about homeliness and domesticity made in a residency at the home of the late conceptual artist John Latham. The gallery is in danger of closure and needs support.
• Flat Time House, London, 5 June until 2 August.
Masterpiece of the week
Jean-Siméon Chardin – The House of Cards (c1736-37)
When will the house of cards collapse? Never. It is frozen in time by oil painting. Chardin’s still and silent composition invites us to concentrate on the boy’s calm intentness as he prepares to add one more card to his fragile creation. Life is arrested by art.
• National Gallery, London.
