In my thesis I analysed J.R.R. Tolkien’s The Hobbit from the as of yet overlooked perspective of memory studies, proposing that the key narrative and character identities of the novel are shaped by cultural traumas (e.g. the memory of Thror’s glorious dwarven kingdom and its destruction by Smaug the dragon, or the Goblins’ of the Lonely Mountain’s defeat by the hands of Thorin and his Company during their travels), which are influenced by the mediality of the narrative world: its embeddedness in orality, print and literacy respectively. In order to prove my hypothesis, first I mapped out how I view the concept of “cultural memory” (after having examined the current relevant academic tableau of The Hobbit). Then, I looked at how orality, literacy and print respectively affect the narrative universe of the novel. Finally, I analysed these narrative and identity shaping cultural memories from the perspective of their traumatic force through which they shape the narrative and its character identities.
