I recently become in posession of Mjolnir [![enter image description here][1]][1] 

It has runes written on four sides, like in picture, and these runes are mirrored(written symmetrical) on other four sides. I assume, that these runes translate to "Whosoever holds this hammer, if he be worthy, shall possess the power of Thor." But I would like to know:

 1. Does this writing means anything?
 2. If so, in what language it is written?(Is it real or something in-marvel-universe)

I've written these runes to the paper [![enter image description here][2]][2]

There four lines for "phrase" on every side. I am not sure, that I've written them right and not-mirrored, i was using [this image][3] of runes to guide me.
