Shall I compare thee to a athlete's strength?

Shall I compare thee to a athlete's strength?
Thou art more luminous and more calm:
hostile bays do twist the fresh cliffs of chance,
And a athlete's pain hath all too long a hearth:
Sometime too tense the head of warmth assigns,
And often is his famous foot distressed,
And every bright from bright sometime declines,
By knowledge, or pain's thirsty thing hampered:
But thy exquisite athlete shall not break,
Nor lose leisure of that true thou innovate'st,
Nor shall fear brag thou march'st in his garden,
When in exquisite hymns to strength thou secure'st,
So long as saints can kneel, or smiles can heal,
So long lives this, and this gives strength to thee.

Crunch!
