[quote]In Norse mythology, Gjallarhorn (Old Norse "yelling horn"[1] or "the loud sounding horn"[2]) is a horn associated with the god Heimdallr and the wise being Mímir. [/quote] [quote]The single mention of Gjallarhorn by name occurs in the Poetic Edda poem Völuspá, wherein a völva foresees the events of Ragnarök and the role in which Heimdallr and Gjallarhorn will play at its onset; Heimdallr will raise his horn and blow loudly.[/quote] I think this makes it from Scandinavia. So the Gjallarhorn is from Denmark, Norway or Sweden.
