Sudden Light

I have been here before,
But when or how I cannot tell:
I know the grass beyond the door,
The sweet, keen smell,
The sighing sound, the lights around the shore.
You have been mine before,-
How long ago I may not know:
But just when at the swallow's soar
Your neck turned so,
Some veil did fall-I knew it all of yore.
Then, now,-perchance again!…
O round mine eyes your tresses shake!
Shall we not lie as we have lain
Thus for Love's sake,
And sleep, and wake, yet never break the chain?
