I'd like to explore this rune a little here - which is a variant of the Odal rune- the Anglo-Saxon name being Ethel (Eđel). I personally refer to this rounded version as Aethel (Aðel) or Othal which is yet another name, and like the others is rooted in the word Noble. As you will no doubt be aware this is the root of the name Adolf or Adal-Wolf, the Noble-Wolf. The English equivalent is Aethelwulf.
Ad Ed Od Ath Eth Oth
The rounded top part of this root is the Oath ring. What we refer to in the squared version of the Odal rune as 'legs' are, in this style, arms. Thus we can see two kinsmen holding the oath ring and swearing oaths and deeds. The word 'oath' is rooted in the Anglo-Saxon root að - and adds to the concept of the Nobility of Blood and Soil.
