Gjallarhorn was one of the Norse Gods most prized possessions. The name means blowing or yelling horn. In modern Icelandic it means mega phone which is exactly what this horn is; an all-natural megaphone. Make a sound into your War horn and it projects and amplifies the sound made. The Vikings used the horn to warn others of impeding battles as well as call people for meetings and dinner. Ewww! I am sure that got confusing and messy at times. This horn has been hand carved and polished. The end features a solid brass mouth piece. Just dont blow into it make an effort with an aaaugha sound, a Ricola, or just speak into it. The possibilities are endless.
