Fire's on

The warning cry that gives this painting its name, "Fire's on," was shouted by railway workers just before a dynamite charge blew apart the rock. Arthur Streeton painted the scene in 1891 at Lapstone Hill in the Blue Mountains, west of Sydney, where crews were carving a railway tunnel straight through solid stone. On the very day he set up his easel, Streeton watched a worker die in one of these blasts, and that grim event lingers beneath the bright surface of the picture. The tunnel mouth sits dark and small at the bottom, with tiny figures scattered across the pale rubble, and above them a huge cliff rises toward a clear blue sky.

Streeton belonged to the Heidelberg School, a group of Australian painters who worked outdoors and tried to capture the fierce sunlight and dry, bleached colors of their own country instead of borrowing looks from Europe. That love of local light shines through in the sun-bleached rock, the scrubby gum trees along the ridge, and the deep blue overhead. The sheer scale of the cliff makes the workers look almost insignificant, a reminder of how tiny people can seem against raw nature.

Beyond its beauty, the painting speaks to the story of a young country pushing forward. The railway blasting through the mountains stood for progress and ambition, but Streeton refused to hide the heat, the dust, and the real danger the men faced. It stays honest about both the striking landscape and the hard, sometimes deadly labor it took to open it up.
