First of all, I should explain what this is. This is the Celtic Tree of Life. It symbolizes balance and harmony. I love the element of lines this design uses. The Celtic knots and branches in tree create a flow. Also, this design shows the element of time
Theese are NOT viking runes. They are an older Rune alphabet, from around year 500 and earlier. They are called the elder futhark. The viking Rune alphabets have usually only 16 runes and there are several different alphabets from that time.
