To Amasia ("At last believe — as")

At last believe — as thou art fair, be good,
Believe I Love; you promis'd me you wou'd.
How can I proofs of my Affection show?
O had I Crowns —
Empires and Worlds, far let those trifles go,
All would I slight, all I can think, for you.
Beyond thy Charms what can Ambition see;
Thou art an Empire, and a World to me.
While Eyes can look, and while thy Beauty blooms,
(And that will be, 'til the Pale Tyrant comes.)
While I have sense to speak, to live, and move,
While I despair, (which must be) while I Love.
While Seas shall roar, while Night and day shall last,
Till the great doom of all Mankind be past,
Still shall my Soul to dear Amasia bow;
And yet she fancies that I Love not now.
O Charming Maid! believe, at last believe,
'Tis all your Sylvius asks you now to give,
Believe that I shall Love you, while I live.
Sure, ev'n from Death my Passion must be free,
Sure, when my Body dies —
Yet the surviving part will think on thee.
What then must come, none, while alive, can prove,
But here, none truly live, who do not truly Love.
O you must needs be full convinc'd I do,
I have no int'rest in the World, but you.
Your self I Court —
And for your self alone, your self I wooe.
