Þórr/Fight with the Giants by Mårten Eskil Winge, 1872

Old Norse mythology informs us that Thor (Old Norse Þórr) is a hammer-wielding god associated with thunder, lightning, storms, oak trees, strength, the protection of the common folk as well as with hallowing and fertility. The cognate deity in wider Germanic mythology and paganism was known in Anglos Saxon England as Þunor and in Old High German as Donar (runic þonar ᚦᛟᚾᚨᚱ), stemming from a Common Germanic *Þunraz (meaning "thunder").

Mighty Thor thunder god

A simple prayer for the good things in life
When I would be weak, help me to be strong;
Protect those I care about in dangerous places
and whom you see worthy of your protection
Wet my appetite for that which is lusty and good
Aid me in my fight for what is just and right!
And help me grow from strength to strength
But most of all teach me, thunder of the gods,
Show me how to throw my own hammer
To slay the giants and nithings who oppose my will!

Thurisaz is not a Þórr rune

Old Norwegian Rune Poem
ᚦ Þurs vældr kvinna kvillu, [Thurs ("Giant") causes anguish to women]
kátr værðr fár af illu. [misfortune makes few men cheerful]

Old Icelandic Rune Poem
ᚦ Þurs er kvenna kvöl [ Thurs ("Giant") is torture of women ]
ok kletta búi  [and cliff-dweller]
ok varðrúnar verr.   [and husband of a giantess]
Saturnus þengill.  [Saturn's thegn]

Anglo-Saxon Rune Poem
ᚦ Ðorn byþ ðearle scearp; [The thorn is exceedingly sharp]
ðegna gehwylcum anfeng ys yfyl, [an evil thing for any knight to touch]
ungemetum reþe manna gehwelcum,[uncommonly severe on all]
ðe him mid resteð. [who sit among them]

Þurs is a name for the giants in Norse mythology. Since when is Thurisaz a Thor rune? New Age bullshit! Cited very often by wiccan pot boiler authors who really should know better as the most dangerous rune? There is no single rune any more powerful or dangerous then the next rune. Runes represent ideas, are possible doorways to unlock certain thoughts or perhaps even a catalyst in aiding a set of circumstances coming into being. Their ability to serve as an oracle is entirely dependant on the reader's interpretation and ability as well as the system used to divine with. No singular rune is any more potent then the next rune nor does the modern idea of "power" factually represent them. This most powerful rune urban legend is pure personal gnosis spread by seriously misinformed new age rune authors and when you consider that no two people are the same, think the same way or indeed can harness, understand runes or even interpret the same way. This is without involving any magic. Outside personal gnosis, I would like to know how any particular rune is any more effective or powerful then the next rune?

In spring 1870 four helmet plate patrices was found by Erik Gustaf Pettersson and Anders Petter Nilsson in a cairn on the lands of the farm No 5 Björnhovda in Torslunda parish, Öland, Sweden.

Týr

According to the Poetic Edda and Prose Edda the Tivar decided to shackle the Fenris wolf  as they feared him but the beast broke every chain they put upon him. Eventually they had the alfars make them a magical ribbon called  Gleipnir which at first sight  appeared to be only a silken ribbon but was made of six wondrous ingredients: the sound of a cat's footfall, the beard of a woman, the roots of a mountain, bear's sinews (meaning nerves, sensibility), fish's breath and bird's spittle. The creation of Gleipnir is said to be the reason why none of the above exist.Fenrir sensed the gods' deceit and refused to be bound with it unless one of them put his hand in the wolf's mouth.

Týr, known for his great wisdom and courage, agreed, and the other gods bound the wolf. After Fenrir had been bound by the gods, he struggled to try to break the rope. Fenrir could not break the ribbon and, enraged, bit Týr's right hand off. When the gods saw that Fenrir was bound they all rejoiced, except Týr. Fenrir would remain bound until the day of the Ragnarök.As a result of this deed, Týr is called the "Leavings of the Wolf"; which is to be understood as a poetic kenning for glory. But during the battle at Ragnarök, Fenrir swallows Odin whole.
