Alphabet Soup

On this chart one can see the origins of both the Brahmi related Siddham texts which is very important to Vajrayana Buddhism and the Runic Alphabet which are important to Celto-Germanic peoples. Their relations to very important writings like Greek, Cyrillic, are vey important to understand as well.
One thing I think is missing from this chart is the influences of Cuneiform. As well as Turkic and Germanic Runes.
