Treasure of God and Sound of Death

No one could deny the fact that treasure like Mjolnir Hammer of Thor or Gungnir Spear of Odin has been gaining so much popularity. Their fame is so great that they overshadow some other less known treasures in Norse mythology. One of such treasures is the Gjallarhorn the Yelling Horn of god Heimdall. No one in Norse mythology loved to hear the sound of this horn, in fact. And the Viking drinking horn is actually the earthly counterpart of the Gjallarhorn of Heimdall.

Gjallarhorn (GJA-lar-horn) was among the most awesome treasures and weapons of the gods. If Thor never went out without his Mjolnir hammer (unless it was stolen by someone who wished a death sentence by Thor), Heimdall never left his Gjallarhorn at home when he went out. Because the sound of Heimdall's horn meant something was approaching or something was happening whether good or bad. 

The reason why the gods did not like the sound of Gjallarhorn was that of its direct connection with Ragnarok Doom of Gods. According to the prophecy, the glory of the gods would end once Ragnarok broke on the sky. During the catastrophe of Ragnarok, the army of giants led by Loki would enter the stronghold of Asgard to wage war. The sound that was set to wake the gods up and pick up their weapons was the sound of Gjallarhorn
