Within the depth-psychology corpus, 'Otto' functions as a multi-valent designator encompassing at least three distinct scholarly personae whose contributions prove formative for the field's engagement with religion, myth, and the creative will. Most prominent is Rudolf Otto (1869–1937), whose Das Heilige (1917) introduced the concept of the numinous — the tremendum et fascinans — as the irreducible core of religious experience. Eliade, Tarnas, and Hillman each register Otto's decisive methodological move: bracketing rational theology to isolate the irrational, affective dimension of the holy. Tarnas situates this project within a broader Uranus-Neptune astrological cycle, linking Otto's work to William James and ultimately to Jung's integration of the numinous into analytical psychology. Walter F. Otto (1874–1958) constitutes the second major figure, approached primarily through Kerényi and the translator Robert Palmer: a classicist-phenomenologist who read Greek religion from the inside, apprehending the gods as genuine spiritual realities rather than allegorical constructs. His Dionysus stands as a landmark of mythological scholarship written in what Palmer calls an 'apocalyptic style.' The third presence is Otto Rank, the psychoanalytic theorist of will and creativity, cited by Yalom as the originator of will therapy and by Freud as a valued editorial collaborator. These three figures — phenomenologist of the holy, mythological classicist, and depth-psychological theorist of volition — collectively define the term's range within the corpus.
Instead of studying the ideas of God and religion, Otto undertook to analyze the modalities of the religious experience... he concentrated chiefly on its irrational aspect.
Eliade identifies Rudolf Otto's methodological revolution — the shift from theological doctrine to the phenomenology of irrational religious experience — as foundational to the modern study of the sacred.

Otto's views were influenced by James's The Varieties of Religious Experience... both Otto's ideas and James's studies influenced the work of Jung, who integrated the concept of the numinous as a critical element in his own psychology.
Tarnas maps a diachronic intellectual transmission — from James through Rudolf Otto to Jung — situating the emergence of the numinous as a concept within a specific astrological and cultural moment.

Not until W. F. Otto, however, did the Nietzschean enlightenment manage to cut through the fanatical German classicist penchant for scholarly overkill... Otto's book, The Homeric Gods: The Spiritual Significance of Greek Religion, is a forerunner of myth studies with a soulful outlook.
Kerényi positions Walter F. Otto as the decisive successor to Nietzsche in classical scholarship, crediting him with pioneering a phenomenologically and spiritually attuned approach to Greek myth.

Palmer's introduction uses Walter F. Otto's critique of Wilamowitz to demonstrate Otto's own commitment to a non-rationalist, experiential reading of Greek religion.

Such is the case with Otto. If his Dionysus is read together with his Die Gotter Griechenlands as it should be, a new theogony of the early world of Greece is created.
Palmer argues that Walter F. Otto's apocalyptic scholarly style, crossing philology and poetry, produces not mere scholarship but a new mythological synthesis of archaic Greek religion.

'Who is Dionysos?' Walter Otto asks. And in replying he remarks: 'The god of ecstasy and terror, of wildness and of the most blessed deliverance — the mad god whose appearance sends mankind into madness.'
Kerényi cites Walter F. Otto's definitive characterization of Dionysus as the paradoxical 'mad god' to anchor his own archetypal reading of the deity's essential nature.

Hillman makes a critical aside noting that Rudolf Otto's key conceptual move — the term 'numinous' — involved transplanting a Roman polytheistic term into a monotheistic theological framework, a fact generally obscured.
