It is a natural conjecture, but Ireland was an anchor point for the Atlantean Global sea trade that reached everywhere and inspired mining and pyramids. All available evidence suggests a veneration of the sun in all their known culture locations. This includes the Americas in paricular.
Ireland was also culturally isolated until the advent of Christianity. It could preserve their system until Christianity arrived. Thus it provides as good a snapshot as possible along with the Inca and the Aztec. Recall also that the earliest reports out of Anatolia tell us the same story.
The overlay of later doctrines has hidden all this, but the Atlantean world dominated through at least a thousand years everywhere during a time in which the non civilized lacked real mobility and posed little threat.
Baal worship is solar and is likely central to the Atlanteans. There has also been an overlay of slander folded into what we know so much can not be trusted there. Nothing so universal could actually sustain aberrations for long..
Was Prayer to the Ancient Solar Gods enough to Change the Renowned Irish Weather?
