  As was recently pointed out by Cadoni, a certain class of two-dimensional
gravitational theories will exhibit (black hole) thermodynamic behavior that is
reminiscent of a free field theory. In the current letter, a direct
correspondence is established between these two-dimensional models and the
strongly curved regime of (arbitrary-dimensional) anti-de Sitter gravity. On
this basis, we go on to speculatively argue that two-dimensional gravity may
ultimatley be utilized for identifying and perhaps even understanding
holographic dualities.
