Benjamin Jonson - The Shadow

FOLLOW a shadow, it still flies you;
   Seem to fly it, it will pursue:
So court a mistress, she denies you;
   Let her alone, she will court you.
   Say, are not women truly, then,
   Styled but the shadows of us men?

At morn and even, shades are longest;
   At noon they are or short or none:
So men at weakest, they are strongest,
   But grant us perfect, they're not known.
   Say, are not women truly, then,
   Styled but the shadows of us men?

Benjamin Jonson
