ELENA FRATTO, B.M. Ejchenbaum fra teoria e scrittura artistica. Il romanzo Marrut v bessmertie (1933). Abstract This dissertation explores the dialogic interactions between literature and literary theory in Boris Eikhenbaums novel Marshrut v bessmertie (1933). Through a narratological and stylistic analysis of Eikhenbaums text, featuring a complex structure of thematic and intonational layers, and the definition of its role within the Russian literary milieu of the late 1920s, this research aims at showing how the novel stages its authors meditations about both the limits and the possibilities of the newly-born Formal method and, at the same time, his searching for a new, post-formalist self-definition.
