Lock up, fair lids, the treasure of my heart

Lock up, fair lids, the treasure of my heart,
Preserve those beams, this age's only light:
To her sweet sense, sweet sleep some ease impart,
Her sense too weak to bear her spirit's might.

And while, O sleep, thou closest up her sight,
Her sight where love did forge his fairest dart,
O harbour all her parts in easeful plight:
Let no strange dream make her fair body start.

But, O dream, if thou wilt not depart
In this rare subject from thy common right:
But wilt thyself in such a seat delight,
Then take my shape, and play a lover's part:
Kiss her from me, and say unto her sprite,
Till her eyes shine, I live in darkest night.
