This thesis compares the novels Doktor Faustus: das Leben des deutschen Tonsetzers Adrian Leverkühn, erzählt von einem Freunde (Thomas Mann) and Mephisto: Roman einer Karriere (Klaus Mann), insofar as they are portrayals of the situation in Germany during the Third Reich. Essentially a comparative study, I explore similarities and differences – thematic and conceptual – by situating both novels in their socio-historical moment (Chapter 1), exploring their conceptions of German national identity (Chapter 2), tracing intertextual connections to other works (Chapter 3), and, finally, examining their understanding of and reliance on art as insofar as it provides the allegorical framework for their respective portrayals of Nazi Germany (Chapter 4).
