WHEN in the chronicle of wasted time
I see descriptions of the fairest wights,
And beauty making beautiful old rime
In praise of Ladies dead and lovely Knights;
Then, in the blazon of sweet beauty's best,
Of hand, of foot, of lip, of eye, of brow,
I see their antique pen would have exprest
Even such a beauty as you master now.
So all their praises are but prophecies
Of this our time, all you prefiguring;
And for they look'd but with divining eyes,
They had not skill enough your worth to sing:
   For we, which now behold these present days,
   Have eyes to wonder, but lack tongues to praise.

William Shakespeare
