Finally, with a little delay due to the health situation, the 2020 register of ARTHOS (n.29 of the new series, Arya Edizioni - OICL), magazine of Traditional Studies founded in 1972 and directed by prof. Renato Del Ponte, on which I begin with a contribution extremely dear to me. Obviously, for me it is an absolute honor to have been invited to collaborate in the annual edition of this magazine which is not very historical to define as historical, and it is doubly so by virtue of the theme of the essay that bears my signature, given that it is a subject to which I personally care a lot: THE WORSHIP OF FAIRY IN CELTIC COUNTRIES: AN ESCATOLOGY OF DEATH AND REBIRTH.
