Megingjord

In Norse mythology, the megingjörð (meaning "power-belt" in Old Norse) is a belt worn by the thunder-god Þórr. The Old Norse name megin means power or strength, and gjörð means belt.

Myths & Legends
According to the Prose Edda, the belt is one of Þórr's three main possessions, along with the hammer Mjǫllnir and the iron gloves Járngreipr. When worn, the belt is described as doubling Þórr's already prodigious strength.

In verse 7 of the skaldic poem Þórsdrápa (Thorsdrapa, Lay of Þórr) written by the 10th-century poet Eilífr Goðrúnarson, in the service of Jarl Hákon Sigurðarson, refers to Þórr's power-belt.

''Harðvaxnar sér herðir halllands of sik falla (gatat maðr) njótr (hin neytri) njarð- (ráð fyrir sér) gjarðar. Þverrir lætr nema þyrri Þorns barna sér Mǫrnar snerriblóð til svíra salþaks megin vaxa.''

The line; njótr njarðgjarðar, literally means "he who benefits from the mighty belt", referring to Þórr's magical belt/girdle of strength/power, Megingjörð.

In Gylfaginning, which is the first part of Snorri Sturluson's Prose Edda after Prologue, verse 45 refers to Þórr's power-belt.

"En er kom at dagan, þá gekk Þórr út ok sér mann, hvar lá skammt frá honum í skóginum, ok var sá eigi lítill. Hann svaf ok hraut sterkliga. Þá þóttist Þórr skilja, hvat látum verit hafði of nóttina. Hann spennir sik megingjörðum, ok óx honum ásmegin. Ok í því bili vaknar sá maðr ok stóð skjótt upp, en þá er sagt, at Þór varð bilt einu sinni at slá hann með hamrinum ok spurði hann at nafni."

The line; Hann spennir sik megingjörðum, ok óx honum ásmegin, means "He girded himself with his belt of strength, and his divine strength grew". ("He" being Þórr).
