Astrophil and Stella 101: Stella is sick, and in that sick-bed lies

Stella is sick, and in that sick-bed lies
Sweetness, that breathes and pants as oft as she;
And grace, sick too, such fine conclusions tries
That sickness brags itself best graced to be.
Beauty is sick, but sick in so fair guise
That in that paleness beauty’ s white we see;
And joy, which is inseparate from these eyes,
Stella now learns (strange case!) to weep in thee.
Love moves thy pain, and like a faithful page,
As thy looks stir, runs up and down, to make
All folks prest at thy will thy pain to assuage;
Nature with care sweats for her darling’ s sake,
Knowing worlds pass, ere she enough can find
Of such heaven stuff, to clothe so heavenly mind.
