Erlkönig (Erlkönig / Erlenkönig)

The Erlkönig, as presented in the provided materials, originates in Johann Wolfgang von Goethe's ballad "Erlkönig" (composed for the Singspiel Die Fischerin, 1782) and functions within that poem as the interlocutor and assailant of a child. The supplied sources do not provide a prior mythic origin or an ethnographic account that situates the figure in older, named folk rites; instead the entity is transmitted and understood primarily through Goethe's literary text and its musical settings (notably Schubert) and subsequent commentary, which label the character a 'king of the fairies' or a demonic fairy-king without offering a systematic prehistory.

The poem gives only a single explicit visual cue: the child asks, "Den Erlenkönig mit Kron' und Schweif?" (literally, the Erlkönig with crown and train/tail), indicating perception of a crown and a trailing garment or appendage. Beyond that line the supplied sources do not provide a detailed physical description; later summaries and commentary infer a courtly, kingly aspect ("king of the fairies"), but such trappings are interpretive extensions rather than additional descriptive details in the texts provided.

In Goethe's ballad the Erlkönig speaks directly to the child, offering enticements — "Du liebes Kind, komm, geh mit mir! / Gar schöne Spiele spiel' ich mit dir; / Manch' bunte Blumen sind an dem Strand, / Meine Mutter hat manch gülden Gewand" — and claims female attendants who will "wiegen und tanzen und singen dich ein." When persuasion fails he threatens force: "Und bist du nicht willig, so brauch' ich Gewalt." The child subsequently reports being touched ("jetzt faßt er mich an"), and by the time the father reaches home "In seinen Armen das Kind war tot," linking the presence or action of the Erlkönig to the child's death. The poem also stages the encounter so that the father's sensory interpretations (a streak of mist, the wind in dry leaves, the grey willows) differ from the child's perceptions, leaving ambiguous whether the cause is purely supernatural assault, a psychosomatic fatal fright, or an interplay between uncanny perception and natural phenomena.
