Further down a Bow is fully formed from K-U.
ARKU (protoindoeuropean for Archer, or Bow and Arrow) form elder runes of a Bow and Arrow.
Here we have a poison of the Kalahari Bushmen, Ancient Egyptian, and Protoindoeuropean in an elder rune form all converging to create part of the Vikings rune set. This form still violates protoindoeuropean's older rule for having AR before KU...so its possible we must put the AR arrow first, and the two bows KU-E next to each other but this brings up another problem. In ancient Egyptian two bows next to each other form the letter Y forming ARY in a Proto-indoeuropean/Ancient Egyptian word mash. Kuare becomes Ary.
In the Egyptian symbol from the Mendez Stele, we have two feathers and an entire warrior armed with bow and arrows (In the rather repetitive form of Y-ARKU). Y-AR is definatly refering to our Kuare using Bushmen of the Kalahari.
