The divergence between solar and lunar (or Asiatic) civilisations is not limited to Christianity versus Heathenism, and must be considered also as a wide analogy, because there is no light without a bit of shadow, and vice-versa. In fact Evola wrote that the East represented also a possibility of restoration "bringing echoes of more ancient virile and solar civilisations, like, for example, the palaeoegyptian and palaeopersian ones".
Yet, in my opinion, Evola was not precise considering solar the ancient Egypt...that on the contrary was solar and lunar in the meantime; anyway, he added that:
"the concept of the Imperium is precisely the great synthesis risen from a reciprocal fecundation of East and West" ('Oriente, Occidente e mediazione romana', La Vita Italiana 1934).
The Imperium was the only entity exceeding the racial and religious differences, a trial aborted already with the political affair between Caesar and Cleopatra.
This said, it's clear that considering Jesus as solar god is valid only in the Egyptian viewpoint: the sun of midnight (the Black Osiris) with his 'scattered limbs', going down to the kingdom of the dead, waiting for the recomposition and the rebirth into the shape of his son, the hawk.
