“It was love at first sight, at last sight, at ever and ever sight.”

Couplet by Christopher Marlowe:
"Where both deliberate, the love is slight:
Who ever loved, that loved not at first sight?

Philip Sidney's sonnet #2, from Astrophel and Stella:
Not at first sight, nor with a dribbèd shot,
Love gave the wound, which, while I breathe will bleed;
But known worth did in mine of time proceed,
Till by degrees it had full conquest got.
I saw, and liked; I liked, but lovèd not;
I loved, but straight did not what Love decreed:
At length to Love's decrees I forced agreed,
Yet with repining at so partial lot.
Now even that footstep of lost liberty
Is gone; and now, like slave-born Muscovite,
I call it praise to suffer tyranny;
And now employ the remnant of my wit
To make myself believe that all is well,
While with a feeling skill I paint my hell. "
