Linguistic Archaeology: An older Rune script...

 What is interesting about Runes is that some of them fit together to create pictograms. Here we have A-R forming an Arrow shaft with arrow-head and fletching.

Further down a Bow is fully formed from K-U.

 This may not seem anymore than a vague self fulfilment desire until we consider that all the possible combinations of the letters of any written language can be assumed to create every word it is ever capable of describing, so if within that combination of Runes are other words from older languages, it is entirely possible that origin is valid.
ARKU (protoindoeuropean for Archer, or Bow and Arrow) form elder runes of a Bow and Arrow.

 Of course fans of Egyptian hieroglyphics might notice that the KU bow looks sort of like the Egyptian symbol for E.

The prospect that there could be a relationship is of interest because it changes the Danish rune language ahead of it.

 A popular name, simply because it is within the possible combination of Danish Runes is UTHAR. Uthar Pendragon is likely a name you are familiar with, except we now know U should be in the form KU in the elder rune form.

 Ku-th-ar is the earlier name form that is almost Protoindoeuropean...

 We also know that ARKU should not be split, so it should now be TH-ARKU.

 In the Scandinavian Rune TH looks a little different to our Danish TH rune. It looks a lot like a Bow (KU).

 If we consider the two bows are incorrectly identified, then the larger KU might be the Egyptian E, and the smaller TH bow is in fact KU.

Now we have KU-AR-E. This may be familiar to you. Kuare is a Poison used by the Bushmen of Kalahari.

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. 
Update: 

 In this case we have Y-AR, the two Egyptian feathers with an Arrow rune.

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.
