Ben Jonson - The Noble Nature

It is not growing like a tree
in bulk, doth make Man better be;
or standing long an oak three hundred year,
to fall a log at last, dry, bald, and sere;

A lily of a day
is fairer in May,
although it fall and die that night-
It was the plant and flower of Light.
In small proportions we just beauties see:
and in short measures life may perfect be.

Ben Jonson
