FIRST-ORDER, 2D, EINSTEIN GRAVITIES

This paper is dedicated to the memory of M. Markov, whose commitment t o Quantum Gravity through the Seminars he organized made possible cont acts across borders when they were most needed. The Palatini variation al method breaks down in 2D: First order forms of the Einstein action do not fix the affinity completely, as they possess an additional, Wey l, invariance absent in the second order versions.
