Sorry, Siofra- I didn’t mean to send you off on a rune goose chase! You’ve been so kind and helpful with sharing the information already here, it is already a great gift to the forum 
And it seems like I jumped ahead and overlapped runes with astrology- I made the assumption that runes would have solar and lunar paths of reading because zoadic signs do, but they really are a wonderfully unique means of divination! While I still see some similarities, it’s clear to me now that runes follow their own rules that stand alone. I have a long way to go in my rune studies! 
Thanks again for all your research and sharing your exploration of the runes!
