Australian landscape painter Arthur Streeton, whose career spanned the nineteenth and twentieth centuries, was a master of light – especially the shimmering dusty glare that defines his often parched homeland. In The Railway Station, Redfern, Streeton took a rare departure from the dazzling sun to paint a rainy day. The cloud that’s cloaking the sky in his artwork is the featureless wet blanket known as Nimbostratus. This is a thick and dark layer of cloud that produces widespread precipitation, often for hours at a time. This cloud rarely features in art, as it is hardly the prettiest of cloud formations. But Nimbostratus can have its own subtle luminous glow, and Streeton manages to capture the quality of this light. Despite its industrial gloom and hunkered-down scurrying cityfolk, the scene is awash in the rain-drenched shimmer of light filtered through Nimbostratus.
