Formalizing the Hero’s Journey

In 1949, Joseph Campbell published The Hero with a Thousand Faces, a work of comparative mythology arguing that heroic myths across cultures, from Sumerian descents to Promethean cycles, betray a single generative sequence he termed the monomyth: a departure, an initiation, and a return, each threshold marking a transformation in the hero's ontological status.

Campbell's framework was shaped decisively by Carl Jung's theory of archetypes, which posited recurring mythological figures as expressions of a collective unconscious transcending individual experience. Campbell gave this psychological machinery a narratological armature, mapping psychic individuation onto the plane of story, a map contemporary filmmakers and game designers still reach for, whether consciously or through convergent intuition.

What makes the monomyth compelling as an object of formal study is the tension between its claim to universality and the irreducible particularity of any given narrative. Every story read through Campbell's stages also resists that reading at determinate points, producing divergences and inversions that constitute the most analytically productive sites of inquiry. It is this generative friction, the gap between the structural template and its concrete realization, that invites a rigorous, systematic treatment capable of capturing both the pattern and its deformations.

  1. 01 Universal narrative grammar — Beneath the surface variety of world mythologies lies a single recurring pattern, the monomyth: a three-act arc of departure, initiation, and return.
  2. 02 Shared vocabulary — Archetypes populate the journey, two worlds define its spatial logic, a threshold divides them, trials test the hero's transformation, and a boon rewards the return.
  3. 03 Variation as structure — Each narrative reshapes, inverts, or omits stages: the symbolic vocabulary changes across cultures and media, but the underlying transformative pattern persists through its own deformations.
“The hero ventures forth from the world of common day into a region of supernatural wonder: fabulous forces are there encountered and a decisive victory is won: the hero comes back from this mysterious adventure with the power to bestow boons on his fellow man.” — Joseph Campbell, The Hero with a Thousand Faces (1949)

A Vocabulary for Myth

The ontology defines a reusable vocabulary at monomyth: that captures the deep structure of Campbell's monomyth. Expressed in OWL and serialized as Turtle, it models the seventeen stages across three acts, the archetypal roles that populate the journey, and the evaluative apparatus needed to assess how faithfully (or how creatively) any given narrative instantiates the pattern. Every analytical judgment, from the quality of a stage's manifestation to the rationale behind a departure from the template, is represented as a first-class, queryable entity rather than a background assumption.

The central modeling pattern is the MonomythExpression, a reification of the interpretive act itself: the structured reading of a particular narrative work through Campbell's lens. Each expression anchors a constellation of StageRealizations, the concrete manifestations of abstract stages within that narrative. A realization carries a prose description of the narrative moment it captures, a position in the story's own sequence (which may diverge from the canonical ordering), and a FitQuality assessment on a six-point scale ranging from Perfect Fit through Strong, Moderate, and Weak to Absent and Inverted, each backed by a numeric score and an optional analytical note.

The treatment of characters draws on Christopher Vogler's The Writer's Journey, a screenwriting manual that deliberately translates Campbell's mythological archetypes into a practical dramaturgy of recurring roles. The ontology formalizes it through the embodiesArchetype property, linking characters to archetypal roles while acknowledging their productive instability: a figure who operates as Mentor in one stage may reveal itself as Shadow in another, and the graph preserves this fluidity as structured, traversable data.

Where the alignment between a narrative and the monomyth template is imperfect, the ontology does not simply record the gap: it models the nature of the departure through three orthogonal divergence classes, all subclasses of CREON's ProductDivergence. A NarrativeDivergence captures what happens when a stage is absent, subverted, compressed, or redistributed across multiple narrative moments. A SequentialDivergence marks when a stage occurs and whether the narrative has displaced it from its canonical position for dramatic or thematic effect. A SemioticDivergence traces how the stage is expressed, underlying the shift in sign systems (from sacred to secular, from mythic to technological, from external threat to internal state) through which the same structural function is realized in a different cultural or medial vocabulary. Each divergence carries a prose rationale documenting the artistic purpose behind the departure, making explicit that imperfect fit is itself an object of analysis, often the most revealing one.

Formalizing a hermeneutic tradition into computational structure risks flattening the very interpretive richness it seeks to preserve. This ontology addresses this tension by treating deviation as constitutive: conformity and subversion, presence and absence, canonical order and displacement are granted equal analytical weight. The deeper question it encodes is how a pattern largely unchanged for millennia has generated such radically diverse stories, and how each creative departure, every inversion or omission, is itself a meaningful act.

The Pattern Persists

The monomyth functions not as a prescriptive template, but as a structural baseline across diverse narrative histories. While certain works align strictly with this framework, others derive their aesthetic or narrative efficacy through deliberate divergence from the expected archetype.

Formalizing Campbell’s framework in OWL bridges literary analysis and computational semantics, establishing a model for the computable humanities. This approach preserves narrative complexity while enabling systematic, scalable comparison. Consequently, the resulting knowledge graphs act as analytical instruments, formalizing how specific cultural and authorial contexts navigate the underlying mechanics of departure, ordeal, and return.

However, the instantiation of these knowledge graphs also highlighted the inherent subjectivity of structural mapping. During the peer-review phase, it became evident that aligning a narrative to a formalized framework is not a purely mechanical extraction. Because researchers evaluate source material through differing critical and analytical paradigms, defining a structural fit constitutes an active, interpretive appraisal of the text.

This interpretive variance manifested directly in the execution of the ontology’s technical architecture. For example, to formalize a missing stage, some researchers consistently paired a monomyth:AbsentFit with an explicit monomyth:NarrativeDivergence, while others treated the AbsentFit itself as a functionally complete ontological statement. Similarly, when a singular thematic subversion impacted multiple stages, certain modelers mapped a single divergence node to several stages, whereas others instantiated distinct divergences or omitted redundant links. Ultimately, these methodological deviations underscore a fundamental characteristic of semantic modeling in the humanities: while an ontology provides a rigorous, standardized schema, the resulting semantic data inherently encodes the critical choices of the human annotator.

Future implementations: formalizing Meta-Convergence

Although our Monomyth ontology doesn't explicitly reuse creon:MetaConvergence, it inherently executes its core mechanism. CreOn defines meta-convergence as the critical appraisal of a creative product's divergence against expected background knowledge to make it functionally or aesthetically effective. Our framework performs this function by using Campbell's monomyth as the structural baseline, while applying specific divergence classes (monomyth:NarrativeDivergence, monomyth:SequentialDivergence, and monomyth:SemioticDivergence) to evaluate creative departures. Both models view these deviations as deliberate, meaningful choices rather than simple errors. To formally implement this connection in the future, we could map our monomyth:FitQuality scores and monomyth:divergenceRationale descriptions directly to the creon:MetaConvergence class.

Expanding the paradigm: beyond Campbell's Monomyth

The ultimate extensibility of this project lies in the potential to expand our foundational schema to transcend the structural limitations of Joseph Campbell's original model. By integrating frameworks like Maureen Murdock's The Heroine's Journey and Kim Hudson's The Virgin's Promise into our ontology.ttl, we could broaden the graph's analytical power to capture deeply internal, relational, and socially disruptive narrative arcs. While Campbell's monomyth maps an outward quest of conquest into the unknown, encoding these alternative frameworks would allow us to query entirely different narrative. Murdock provides a potential "feminine counter-arc" that tracks inward descent to integrate split psychic polarities, while Hudson's model captures transformation born from radical self-expression against a conformist community. Ultimately, by formalizing these alternative structures as linked data in the future, we could empower the ontology to successfully process genres that the traditional monomyth struggles with, proving that narratives prioritizing authenticity and inner balance are just as structurally rigorous as tales of external triumph.

Potential research: querying the Monomyth

By populating the knowledge graphs with diverse narrative in the future, would enable us to formulate complex research questions that query divergences across multiple cultural axes.

We could run SPARQL queries to discover, for instance, how the monomyth:SemioticDivergence shifts from literal magic to psychological trauma across centuries of storytelling, or whether authors of different genders systematically invert specific archetypes. Specifically, the structured nature of this dataset would allow researchers to track narrative shifts over time (mapping historical trends and the evolution of specific divergences), across space (contrasting Western and Eastern structural traditions), through distinct media (comparing structural constraints in literature, film, comics, and music), and across gender (analyzing how the gender of the author or protagonist dictates specific divergences).

Ultimately, this framework has the potential to transition the Monomyth from a static literary theory into a dynamic, quantitative research tool, ready to reveal exactly how modern culture bends ancient mythologies to reflect its own realities.

LLM-aided graph modeling

To rapidly scale the population of our ontology without sacrificing structural integrity, we employed an LLM-assisted knowledge grounding technique using Claude and Gemini. By supplying our baseline OWL ontology alongside a "gold-standard" exemplar (The Matrix), we created a short prompt to draft new narrative knowledge graphs.

The results provided a fascinating case study in LLM limitations: for newer or less famous works, analytical accuracy plummeted as the models confidently hallucinated plot points to force a fit into Campbell's framework.

Ultimately, LLM generation serves as a first-pass scaffolding, requiring human-in-the-loop revision. The AI can build the graph's syntactic skeleton, but identifying why an author deliberately subverted an archetype remains a human intellectual exercise.

The Monomyth in action
  • help
    Which monomyth stage remains the most stable and consistent across its realizations?
    Result The Crossing of The First Threshold. Because crossing into the unknown is a fundamental prerequisite for both the plot's momentum and the hero's growth, this stage's core function remains intact even when authors heavily subvert its traditional tropes.
    View on SPARQL explorer
  • help
    Which monomyth stage is the most mutable and exposed to divergences?
    Result Woman as the Temptress. The stage's gendered framing forces virtually every contemporary retelling into semiotic translation, recasting temptation as internal crisis, ideological seduction, or moral compromise rather than literal feminine enticement.
    View on SPARQL explorer
  • help
    Which stage is most narratively variable, revealing greater conceptual flexibility across works?
    Result Refusal of the Return. The stage presupposes a two-world cosmology and a homecoming that contemporary narratives often eliminate entirely, since transformation renders the ordinary world unrecognizable or because the hero's departure was itself the destination.
