Thurisaz is the sound “th”
Anglo-Saxon Rune Poem (from ragweedforge.com)
The thorn is exceedingly sharp,
an evil thing for any knight to touch,uncommonly severe on all who sit among them
Thurisaz reversed is the rune for Sunday. It is the protective power of thurisaz, it’s thorns and roughness turned out, making a difficult path for misfortune.
One of the commonly accepted meanings of thurisaz is that it relates to Thor, probably the most popular deity of the Northern Tradition. From comics, to depictions, and probably the most commonly recalled deity, Thor seems to get everywhere. I saw commonly accepted because it is a meaning I do not accept. I personally don’t see it, and at least from what remains of information written down about Thurisaz, nothing in it indicates to me that it was the rune for Thor. It’s name usually appears in conjuction with curses typically. I think it makes sense to say that Thor was probably not routinely called upon for cursing others. That sounds more like his names, the Giants, or by one of their oldest names, the Thurs. It is the Thurs that I see thurisaz identifying, and it is part of their feared power that comes through with any form of thurisaz. Depending upon it’s position that power is either against you or for you. As a single rune reading, that might be identified by it’s upright or reversed position. In a spread style or a casting, it depends upon how it falls in relation to where the querent is most strongly indicated.
Today, it is like the idea of like fighting like. The powers of misfortune that might harm you, are kept at by other powers of misfortune.
