A reminds Д and a reminds д and I meet the eery similarity between the two on many levels (probably some of them are caused on similarity between a and d and then the misreading multiplied from there)


Notice how a and r use the D shape, it also links this file to R~D

(R looking like D) and the next image made me pay attention to both signs in reverse being A (and that is A~D controversy)
And there's another interesting interpreation of those signs:

But that controversy is a part of the larger one:




Old Persian:
𐎠 a
 𐎭 d



D of the demon
A of the angel
