Out upon it, I have lov'd
Three whole days together;
And am like to love three more,
If it prove fair weather.

Time shall molt away his wings
Ere he shall discover
In such whole wide world again
Such a constant lover.

But the spite on't is, no praise
Is due at all to me:
Love with me had made no stays
Had it any been but she.

Had it any been but she
And that very face,
There had been at least ere this
A dozen dozen in her place.

Sir John Suckling
