From Seal Morning (1957), by Rowena Farre.

He went on to say that according to old Celtic occult lore we belong in the morning of our lives, or childhood, to the sea; in the afternoon, or maturity, to the land; and in the evening, or old age, to the air. Only after death do we mingle with and belong to all three elements. Then Time is undifferentiated, like a great wave which never breaks, like a wind blowing strong and free forever, like a vast range of hills unbroken by any plain. In this eternal time our strength does not ebb or flow and no moment is more propitious than another.
