Goethe based his poem ‘Erlkönig’ on a Danish folk ballad about the king of the elves and his daughters, which had been translated into German by Johann Gottfried Herder as ‘Erlking’s Daughters’. The ballad’s proto-Romantic content is rooted in popular notions of the supernatural. Schnorr uses gestures to convey the threat inherent in the story, whereas Schwind bathes the scene in a pale half-light and emphasises the demonic aspect. In places, the outlines Schwind drew with rapid, flickering strokes of the pen show through the thin, loosely applied paint.
