The book of rain

In visions of the night, like dropping rain,
Descend the many memories of pain
Before the spirit's sight: through tears and dole
Comes wisdom o'er the unwilling soul-
A boon, I wot, of all Divinity,
That holds its sacred throne in strength, above the sky!

Aeschylus, 525 B.C. – 456 B.C.
