Здесь прошелся загадки таинственный ноготь

Here the Trace:

Here the trace of enigma's strange fingernail shows.
"It is late. Let me sleep, and at dawn I’ll reread
And then all will be clear. Till they wake me, there’s none
Who can move the beloved as I move her, indeed!”

How I moved you! You bent to the brass of my lips
As an audience stirred by a tragedy thrills.
Ah, that kiss was like summer. It lingered, delayed.
Swelling slow to a storm as it topples and spills.

As the birds drink, I drank. Till I swooned still I sucked.
As they flow through the gullet, the stars seem to stop.
But the nightingales shuddering roll their bright eyes.
As they drain the vast vault of the night, drop by drop.
