“Night had come—night that she loved of all times, night in which the reflections in the dark pool of the mind shine more clearly than by day.”

Context: You could not tell, and yet it looked as if
The shore was lucky in being backed by cliff,
The cliff in being backed by continent;
It looked as if a night of dark intent
Was coming, and not only a night, an age.
Someone had better be prepared for rage.
There would be more than ocean-water broken
Before God's last Put out the Light was spoken.

"A Generation" [Yidai ren]

O guiding night! O night more lovely than the dawn!
O night that has united the Lover with his beloved, transforming the beloved in her Lover.
Variant translation by Kieran Kavanaugh and Otilio Rodriguez (1991)
Oh night thou was my guide
Oh night more loving than the rising sun
Oh night that joined the lover to the beloved one
transforming each of them into the other.
Variant adapted for music by Loreena McKennitt (1994)
Dark Night of the Soul

I'm in Love With You
Song lyrics, Jackrabbit Slim (1979)

Non c’è giorno senza tenebre e notte senza luce.
