Tarnhelm is a magic helmet in Richard Wagner's Der Ring des Nibelungen (1848-1874). It was crafted by Mime at the demand of his brother Alberich. It is used as a cloak of invisibility by Alberich in Das Rheingold (1869). It also allows one to change one's form:
- Alberich changes to a dragon and then a toad in Das Rheingold, Scene 3
- Fafner changes to a dragon at the end of Das Rheingold and appears thus in Siegfried Act II. (It is never made clear whether Fafner actually used the Tarnhelm to transform, or simply transformed as many giants and gods did in the myths. There is also no Tarnhelm present in the original Andvari myth from Reginsmál in the Poetic Edda from which Wagner drew inspiration for this scene.)
- Siegfried changes to Gunther's form in Götterdämmerung Act I, Scene 3.
Finally, it allows one to travel long distances instantly, as Siegfried does in Götterdämmerung Act II, Scene 2.
Usage examples of "tarnhelm".
Siegfried suddenly comes from the river bank tucking into his belt the Tarnhelm, which has transported hi from the mountain like the enchanted carpet of the Arabian tales.
Spells using the Tarnhelm Effect are very similar in structure to the aversion spell you met at the door to this room.
I correct in assuming that the spell Master Ewen had cast upon his own blade was in some manner a utilization of the Tarnhelm Effect?
I know what the Tarnhelm Effect is, of course, since I have come across mention of it in my studies, but its utilization and theory are quite beyond me.
Why dont you take another comfortable passenger train back to New Berlin, and call Tarnhelm to say that you will be one day late?
