Masterpiece of the week

Anna and the Blind Tobit (c1630) by Rembrandt
Light and dark shape a space in this mesmerising work of art. The Biblical story of Tobit tells how he is blinded and his family reduced to poverty as a test from God. Here Tobit and his wife Anna share their suffering in a humble interior probably much like the homes of poor peasants at the time it was painted. Rembrandt sculpts the dark, soft atmosphere of the room so that the air itself seems tangible. Through this velvety chiaroscuro he suggests the blind inner world of Tobit. Is true vision optical or is it in the mind’s eye? Rembrandt feels his way towards the shadowy truth.
• National Gallery, London
Image of the week

Millicent Fawcett by Gillian Wearing
London’s Parliament Square has its first statue of a woman: Millicent Fawcett, the suffragist who fought for women’s right to vote. The unveiling was attended by those who benefit from her legacy – including a prime minister, a bishop and women leaders from many walks of British life.
