Aesc is the dipthong “ae”
Anglo-Saxon Rune Poem (from ragweedforge.com)
The ash is exceedingly high and precious to men.
With its sturdy trunk it offers a stubborn resistance,though attacked by many a man.
Aesc reversed is the rune for today, the day of Odhinn. To me Aesc is the rune of the upper worlds, and of the primal substance (or essence) from which men (and ultimately all things) are created from. To be drawing upon this primal substance brings ecstasy, like being touched by Divinity, inspiration, but it can also bring madness and escapist obsession. When it is reversed, it can mean the absence of those things. Today however, Aesc reversed to me indicates that this primal substance is being grounded, channeled down into the middle world, to vitalize and rejuvenate the manifested. The inspiration, the primal essence is still there, but it is becoming crystallized as it comes into the middle world. The frenetic and powerful energy is cooled off, so that it can be made useful.
