In the stories there is scarcely any part of Ireland which is not linked, almost geographically, with its scenery.
Even the ancient gods have retired from the coast to live in the pleasant green hills or by the wooded shores of the great lakes or in hearing of the soft murmur of the rivers.

This business of the sea, this varied aspect of the land, crept into the imagination of the Irish, and were used by them to embroider and adorn their poems and tales.

They do not care as much for the doings of the sky.

There does not seem to be any supreme god of the heaven in their mythology.
Neither the sun nor the moon are specially worshipped.

There are sun-heroes like Lugh, but no isolated sun-god.
