  We submit a classical unification of the special and general relativities via
the new isominkowskian geometry in which the two relativities are
differentiated by the basic unit. We then show that the unification admits an
operator image in which gravitation verifies the abstract axioms of
relativistic quantum mechanics under a universal symmetry which is isomorphic
to the Poincar\'{e} symmetry. The compliance of the unification with available
experimental data is indicated. This study has been permitted by the recent
achievement of sufficient mathematical maturity in memoir$^{3f}$, axiomatic
consistency in memoir$^{3t}$ and generalized symmetry principles in
memoir$^{4v}$. More detailed studies are presented in the forthcoming
paper$^{3u}$.
