ABSTRACT.  We study the Euclidean sine-Gordon field theory on  the plane with
(beta)  < 16(pi)/3  and 
an interaction density confined to a finite square.
For (beta) = 4(pi) we construct  correlation functions for the field
:sin (phi): and show that   they are equal
to  the pseudoscalar (psibar)(Gamma)(psi)  correlation functions for a  free
fermion theory  with  mass term confined to the finite square.
