NARRATOR: The three paintings displayed at this end of the gallery illustrate a biblical theme, the Last Judgement. They were painted by John Martin, who initially trained as a glass painter but became the most popular British artist of his day. Let’s start with the one on the right. Tate Britain curator Martin Myrone. MARTIN MYRONE: It’s probably the most famous, the best known of John Martin’s paintings, The Great Day of His Wrath, produced towards the end of his life, and showing a scene of utter catastrophe and destruction at the end of the world as prophesied in the biblical Book of Revelation. Here you see the earth torn apart, the moon turning to blood, and whole cities being convulsed in upon themselves, with humanity mercilessly torn apart in the foreground. It is part of a triptych of paintings sent out on tour in 1854, when John dies. By 1861 it is claimed that 'The Great Day of His Wrath' and the accompanying pictures had been seen by as many as 8 million people; so apparently more than 1 in 3 people had seen these pictures. NARRATOR: And how exactly were they displayed? MARTIN MYRONE: We know these paintings were shown dramatically by dowsed light, and they were shown not only in gallery spaces, but also in music halls and in theatres, and in civic spaces; places which wouldn’t normally see art. We know also that there were occasionally descriptive lectures, so there would be a mustachioed gentleman who would point out the details of the paintings and dramatise their content.
