The wall is artifice, is illusion,
a masque to keep the forest
at bay — at least it seems that
way until the hunter gets his
arm stuck in it & Newton's
law of universal gravitation
kicks in. Or, equally, kicks
out. Allegorically, this could be
a depiction of the "first great
unification," a realization of
the attraction of particles. Or,
if you're so inclined, another
allegory, where Isaac Newton
is the hunter, presenting the 1st
Book of his Principia to the
Royal Society, & Robert Hooke
is represented by the wall, ac-
cusing Newton of plagiarism
&, as punishment for the theft,
attempting to take his hand off.
