To recapitulate, the Dagda Mor was a divine title given to a hero named Eocaidh, who lived many centuries before the birth of Christ, and in the depths of the pre-historic ages. He was the mortal scion or ward of an elder god, Elathan, and was interred in some unknown grave—marked, perhaps, by a plain pillar stone, or small insignificant cairn.
The great tumulus of New Grange was the temple of the divine or supernatural period of his spiritual or imagined career after death, and was a development by steps from that small unremembered grave where once his warriors hid the inurned ashes of the hero.
What is true of one branch of the Aryan family is true of all. Sentiments of such universality and depth must have been common to all. If this be so, the Olympian Zeus himself was once some rude chieftain dwelling in Thrace or Macedonia, and his sublime temple of Doric architecture traceable to some insignificant cairn or flagged cist in Greece, or some earlier home of the Hellenic race, and his name not Zeus, but another; and Kronos, that god whom he, as a living wight, adored, and under whose protection and favour he prospered.
