Venere, particolare Botticelli

Shall I compare thee to a Summer's day?
Thou are more lovely and more temperate:
Rough winds do shake the darling buds of May,
And Summer's lease hath all too short a date:

Sometime too hot the eye of heaven shines,
And often is his gold complexion dimm'd;
And every fair from fair sometime declines,
By chance or nature's changing course untrimm'd:

But thy eternal Summer shall not fade
Nor lose possession of that fair thou ow'st;
Nor shall Death brag thou wander'st in his shade,

When in eternal lines to time thou grow'st:
So long as men can breathe, or eyes can see,S
o long lives this, and this gives life to thee.

William Shakespeare, Sonnet XVIII, Shall I Compare Thee?
