Abstract
Piotr Rawicz's novel Le sang du ciel depicts a Jewish protagonist, Boris, who manages to escape the Nazi genocide and, as a result, doubts his own legitimacy to bear witness to the other Jews' fate during that period. His difficult relationships with the Jewish community find expression in an intertextual construction, founded on the ontocosmology developed in Plato's Timaeus. Boris uses—and sometimes perverts—Plato's world vision both to measure his own inauthenticity and to define new ways of creating a state of "fusion" with the "beings" surrounding him. Another technique to overcome Boris's inability to testify is the use of a frame narrative, which, moreover, sheds new light on the protagonist's identity as a witness.
