Since it was unveiled just months after the end of the first world war, John Singer Sargent’s monumental painting Gassed has been hailed as an era-defining artwork, going on to be the most popular in the collection of the Imperial War Museum in London.
Enormous in scale – it is more than 6 metres wide – the painting depicts lines of soldiers, blinded by mustard gas, picking their way through a crowded battlefield, each with a hand on the shoulder of the man in front. In later decades many viewers have admired Sargent’s uncharacteristic use of a greenish-yellow colour scheme, emphasising the flat khaki of the soldiers’ uniforms and perhaps even a queasy atmosphere tinged with poison gas, in which two men lean over to vomit.
