Altdorfer was the pioneer painter of pure landscape, making them the subject of the painting, as well as compositions dominated by their landscape. He believed that the human figure shouldn't disrupt nature, but rather participate in it or imitate its natural processes. Taking and developing the landscape style of Lucas Cranach the Elder, he shows the hilly landscape of the Danube valley with thick forests of drooping and crumbling firs and larches hung with moss, and often dramatic colouring from a rising or setting sun. His Landscape with Footbridge (National Gallery, London) of 1518–1520 is claimed to be the first pure landscape in oil.
