Hrungnir is a figure from Norse mythology, depicted as a giant (or Jötunn) known for his immense strength and his encounter with the god Thor. Hrungnir is described as having a heart made of hard stone and a massive head, often depicted riding a horse made of stone. His name is derived from Old Norse and can be translated as "the drum" or "the thunderer," though the exact etymology is debated. In Hebrew, Hrungnir can be transliterated as הרונגניר. In German, he is known as Hrungnir, and in French, he is referred to as Hrungnir. The most notable account of Hrungnir is found in the Prose Edda, where he challenges Thor to a duel after being provoked by the god's servants. Despite his formidable strength, Hrungnir is ultimately defeated by Thor, who uses his hammer, Mjolnir, to shatter the giant's stone heart. This myth highlights the eternal struggle between the Æsir (the Norse gods) and the Jötnar (the giants), a central theme in Norse mythology.
