A Seascape. The coast of the Island of Rügen in Evening Light

Johan Christian Dahl painted A Seascape, The Coast of the Island of Rügen in Evening Light around 1818, demonstrating his mastery of coastal marine subjects alongside his better-known Norwegian mountain and fjord landscapes. Rügen — the large Baltic island that was also significant in the work of Caspar David Friedrich — gave Dahl a subject combining the atmospheric marine light of the Baltic with the dramatic chalk cliffs that made the island's coastline famous. His plein air approach to the coastal landscape, recording the specific quality of Baltic evening light with directness and confidence, anticipates aspects of the naturalistic tradition that would develop in both Scandinavia and France.

Dahl renders the evening light on the sea with careful atmospheric observation, capturing the warm tones of sunset reflected in the water. The composition combines precise observation of the coastal landscape with the Romantic sensitivity to transient light effects.
