Three Shakespeare-Songs , opus 164

My glass shall not persuade me I am old,
So long as youth and thou are of one date;
But when in thee time's furrows I behold,
Then look I death my days should expiate.
For all that beauty that doth cover thee,
Is but the seemly raiment of my heart,
Which in thy breast doth live, as thine in me:
How can I then be elder than thou art?
O! therefore love, be of thyself so wary
As I, not for myself, but for thee will;
Bearing thy heart, which I will keep so chary
As tender nurse her babe from faring ill.
  Presume not on thy heart when mine is slain,
  Thou gav'st me thine not to give back again.

Mine eye hath play'd the painter and hath steel'd,
Thy beauty's form in table of my heart;
My body is the frame wherein 'tis held,
And perspective it is best painter's art.
For through the painter must you see his skill,
To find where your true image pictur'd lies,
Which in my bosom's shop is hanging still,
That hath his windows glazed with thine eyes.
Now see what good turns eyes for eyes have done:
Mine eyes have drawn thy shape, and thine for me
Are windows to my breast, where-through the sun
Delights to peep, to gaze therein on thee;
  Yet eyes this cunning want to grace their art,
  They draw but what they see, know not the heart.
