Clarke has said that she hopes the magic is as realistic as that in Le Guin's Earthsea trilogy. This realism has led other reviewers, such as Polly Shulman, to argue that Clarke's book is more of an historical fiction, akin to the works of Patrick O'Brian. As she explains, "Both Clarke's and O'Brian's stories are about a complicated relationship between two men bound together by their profession; both are set during the Napoleonic wars; and they share a dry, melancholy wit and unconventional narrative shape."

As well as literary styles, Clarke pastiches many Romantic literary genres: the comedy of manners, the Gothic tale, the silver-fork novel, the military adventure, the Byronic hero, and the historical romance of Walter Scott. In fact, Clarke's novel maps the literary history of the early nineteenth century: the novel begins with the style and genres of Regency England, an "Austenian world of light, bright, sparkling dialogue and well-mannered gentility", and gradually transforms into a dark, Byronic tale. Clarke combines these Romantic genres with modern ones, such as the fantasy novel, drawing on the works of J. R. R. Tolkien, Philip Pullman, T. H. White, and C. S. Lewis. As Maguire notes, Clarke includes rings of power and books of spells that originate in these authors' works. In contrast, Sacha Zimmerman suggests in The New Republic that while Tolkien's world is "entirely new", Clarke's world is more engaging because it is eerily close to the reader's. Although many reviewers compare Jonathan Strange & Mr Norrell to the Harry Potter series, Annie Linskey contends in The Baltimore Sun that "the allusion is misleading": unlike J. K. Rowling's novels, Clarke's is morally ambiguous, with its complex plot and dark characters. Themes Friendship Reviewers focus most frequently on the dynamic between Norrell and Strange, arguing that the novel is about their relationship. In her review for the Times Literary Supplement, Roz Kaveney writes that the two illustrate Harold Bloom's notion of the "anxiety of influence" in addition to romantic friendship. The two are a "study in contrasts", with Norrell "exceptionally learned but
