Zwei Schiffe auf bewegter See, links eine Tonne 

"Zwei Schiffe auf bewegter See, links eine Tonne" (Two Ships on a Rough Sea, a Barrel to the Left) is a wash drawing by Martinus Schouman, a Dutch artist active in the late 18th century. The drawing, now in the collection of the Städel Museum, features two ships navigating a choppy sea under a cloudy sky. This maritime scene, typical of the Dutch Golden Age, reflects the nation's strong seafaring tradition and commercial ties to the world. Schouman captures the movement of the waves and the ships with loose, expressive strokes, contributing to the overall sense of drama and dynamism in the artwork.
