Fresco by Gustav Heidenreich illustrating Norse mythology in the "Fatherland Hall" of the New Museum, Berlin.  On the left, four water nixes loll at a lakeshore.  The reclining nix in the foreground is picking branches from hanging leafy boughs.  Beside her, a second nix is propped on her harp.  The two nixes in the background gaze pensively across the lake.  The central field shows a dragon in the shape of a griffon, with an eagle's head, eagle wings, and a lion's body.  Hissing and with wings spread, he guards over a treasure comprising a helmet, a shield, a sword, a crown, rings, and coins.  On the right side, two giants combat a dragon.  They are trying to throw boulders into its open maw.
