Art, Nature and Biology

The beauty in nature can be explained
by physics, chemistry, biology, maths.
It can only be truly described
Through art;
   The stroke of fine horse's hair
   or a sharpened feather
   fine and fair.

And whether intrinsic or learned
the artist's guile is guided by maths.
A shrewd eye shapes and forms a scene
as a lucid mind equates.
  The stroke of fine horse's hair
   or a sharpened feather
   fine and fair.
