Desire, though thou my old companion art,
And oft so clings to my pure love, that I
One from the other scarcely can descry,
While each doth blow the fire of my heart;

Now from thy felloswhip I needs must part,
Venus is taught with Dian's wings to fly:
I must no more in thy sweet passions lie;
Virtue's gold now must head my Cupid's dart.

Service and honor, wonder with delight,
Fear to offend, will worthy to appear,
Care shining in mine eyes, faith in my sprite:

These things are left me by my only dear;
But thou, Desire, because thou wouldst have all,
Now banish'd art. But yet alas how shall?

Sir Philip Sidney
