Painters of the Romantic era like John Martin and Francis Danby were influenced to create large and highly dramatic pictures by the sensational dioramas and panoramas of their day. In one case, the connection between life and diorama art became intensely circular. On 1 February 1829, John Martin's brother Jonathan, known as "Mad Martin," set fire to the roof of York Minster. Clarkson Stanfield created a diorama re-enactment of the event, which premiered on 20 April of the same year; it employed a "safe fire" via chemical reaction as a special effect. On 27 May, the "safe" fire proved to be less safe than planned: it set a real fire in the painted cloths of the imitation fire, which burned down the theater and all of its dioramas.
