Gjallarhorn

Gjallarhorn (Old Norse: [ˈɡjalr̩horn], "hollering horn" or "the loud sounding horn") was a large lur located in the castle at the top of the Heavenly Mountain, which is looked after by Heimdall. As the prophecy of the völva foretold, when Ragnarok was upon the world, and the jotunns were approaching Asgard, Heimdall blew into the horn, which can be heard across all of Asgard, and signalled the aesir and the beginning of the battle that would spell the end of the world. Gjallarhorn hung from two chains at a embrasure facing outwards towards the lands of Asgard.

In the mythology, it is not clear what kind of instrument gjallarhorn was. Some people interpret it to be a horn like the ones the Norse used to drink from, but longer, and others that it is a lur. Chapter 25 of Gylfaginning even calls it a "trumpet". According to the mythology, in chapter 14 of Gylfaginning in Snorri Sturlusson's Prose Edda, Heimdall drinks of the water from the Well of Mimir from the gjallarhorn, making him wise. In chapter 25 of Gylfaginning, Snorri also writes that gjallarhorn's "blast can be heard in all worlds" of the Norse cosmology.
