Sitting once, rapt with delight

Sitting once, rapt with delight,

In my fairest mistress' sight,

I took pleasure to compare

Her eyes' whiteness to the air.

That which compassed in the ball,

I did purest water call;

And the pretty inward round

I styled earth. But O, I found,

While some part I did desire

For to liken unto fire,

Ere I knew from whence it came,

I myself grew all aflame.
