"I look'd and saw within"
di John Dryden (1631-1700)

I look'd and saw within the Book of Fate,
Where many days did lowr
When lo one happy hour
Leapt up, and smil'd to save thy sinking State;
A day shall come, when in thy power
Thy cruel Foes shall be;
Then shall thy Land be free,
And thou in peace shalt reign.
But take, O take that opportunity,
Which once refus'd will never come again.
