This paper addresses the question of whether the character of Heathcliff from Emily Bronte’s 1847 literary classic Wuthering Heights suffers from post-traumatic stress disorder, a topic that has been partially neglected due to the fact that in the Victorian era the concept of trauma was considered to be a “woman’s disease.” In various analyses, Heathcliff is often viewed from a negative angle – as an arrogant and vindictive man – and specific mental disorders or illnesses are not adequately studied. However, given the presence of several symptoms of PTSD, it is appropriate to examine the possibility that Heathcliff suffers from this disorder. The paper first offers a broad introduction of Heathcliff’s life. It then characterizes Heathcliff as a Byronic hero. The following chapter focuses on the link between this type of hero, trauma, and PTSD, which then leads to the analysis of some anomalies in Heathcliff’s behavior that could be observed as symptoms of PTSD, as well as the possible reasons for their development. Ultimately, the paper highlights that Heathcliff does indeed suffer from posttraumatic stress disorder, the primary cause of which is the trauma he suffered from abuse in his youth and the death of Catherine.
