the rune circle is the runic alphabet, Peace - Viking Symbol A Rune based symbol meaning "PEACE" - I don't know what hot blooded viking back in the day cared about peace, well peace under their own terms and thinking i guess, which could be very different to today's concept of peace? But its nice to know that perhaps the inclusion of such a symbol reveals a different side to the Viking pysche' that may be different to what we have been lead to believe?
This Symbol is made up of what appears to be a "R" ("Raidho) backwards and joined with a "B" .
When an "R" is placed backwards (Merkstave) it then means: Crisis, rigidity, stasis, injustice, irrationality. Disruption, dislocation, demotion, delusion, possibly a death.
Therefore, possibly the combination of a backward "R" and a "B" binds both life and death, where new life comes from death and visa versa, or it speaks of the after life, though Viking burials have included weapons, as life after death was considered no different to live on earth some times?
This is very similar to the BLUETOOTH symbol people are undoubtably familiar with?
"The word Bluetooth is an anglicised version of Danish Blåtand, the epithet of the tenth-century king Harald I of Denmark and parts of Norway who united dissonant Danish tribes into a single kingdom. The implication is that Bluetooth does the same with communications protocols, uniting them into one universal standard.
The Bluetooth logo is a bind rune merging the Younger Futhark runes H-rune (Hagall) and Runic letter berkanan.svg (Bjarkan) , Harald's initials."
