Abstract: Compared to a Gide capable of transforming, without ever becoming distorted, Claudel shows less flexibility. This induces, in their correspondence, a singular play, the gidian flow bypassing the Claudelian reef, Claudel failing to seal a leaking material. If the frontal debate on faith and conversion stiffens Claudel in his dogmatic certainties and plunges Gide into turmoil, the literary question on the contrary, even if the agreement is not total, seems to unite and federate the two men.
