The Sea of Ice is an 1823–1824 oil-on-canvas painting by the German Romantic painter Caspar David Friedrich. It depicts Friedrich's interpretation of an Arctic landscape, with a shipwreck half-buried in the ice. Its radical composition and subject matter were unusual for their time and the work was met with incomprehension. It has been retrospectively considered one of Friedrich's masterpieces. Caspar David Friedrich, 1823 — painted at 49. Canvas and oil paint. 96.7 × 126.9 cm. In the Hamburger Kunsthalle. Romanticism. Wiki link
