Sir John Rhys, Celtic Folklore: Welsh and Manx…
“ Still, we have far fewer propositions to lay down than questions to ask: thus to go no further afield than the well-known stories attaching to the name of Heracles, how many of them are Aryan, how many Semitic, and how many Aryan and Semitic at one and the same time? That is the sort of question which besets the student of Celtic mythology at every step; for the Celtic nations of the present day are the mixed descendants of Aryan invaders and the native populations which those Aryan invaders found in possession. ”
