Within the depth-psychology corpus, sunset functions as a richly overdetermined threshold symbol standing at the intersection of solar mythology, the individuation cycle, and the archetype of death-and-rebirth. Jung's treatment in Symbols of Transformation is foundational: the westward journey into the sunset constitutes the sun-hero's descent into the maternal depths, the night-sea voyage that precedes renewal. Hiawatha's sailing into the 'fiery sunset' toward the 'Islands of the Blessed' exemplifies this movement as both mythological narrative and psychological template for the ego's surrender to the unconscious. The ancient Chinese reading of sunset in the I Ching as a metaphor for old age and the natural acceptance of life's end complements Jung's solar symbolism with an Eastern wisdom tradition. Jung's field-observation among the Elgon peoples adds an ethnographic dimension, revealing how sunset marks a literal cosmological threshold beyond which the optimistic dayworld yields entirely to dark, chthonic powers. In Jungian solar psychology more broadly—visible in Moore's reading of Ficino—the setting sun figures the 'dark night of the soul,' a necessary downward movement within the rhythm of light and darkness. Moore's King, Warrior, Magician, Lover treats the sunset aesthetically, as a practical doorway into the Lover archetype. Across these registers, sunset is never merely a natural phenomenon but a psychically charged liminal moment encoding transition, mortality, and the promise of transformation.
Westward, westward, Hiawatha / Sailed into the fiery sunset, / Sailed into the purple vapours, / Sailed into the dusk of evening… To the Islands of the Blessed, / To the kingdom of Ponemah, / To the land of the Hereafter!
Jung reads Hiawatha's westward voyage into the sunset as the archetypal sun-hero's descent into the maternal depths, equating the setting sun with death, rebirth, and passage to the realm of the Hereafter.

After sunset, another world took over—the dark world of the Ayik, who is everything evil, dangerous, and terrifying. The optimistic philosophy ends and a philosophy of fear, ghosts, and magical spells for averting the Evil One begins.
Jung's ethnographic account of the Elgon people demonstrates how sunset operates as a cosmological threshold separating the dayworld of the father-god from the nocturnal world of dark, chthonic powers.

The ancient Chinese used sunset as a metaphor to indicate old age. The sun declines quickly, like the end of one's life… When one ages, one should beat the earthen pot, sing, and fully enjoy the blessings of life.
The I Ching tradition explicitly encodes sunset as a symbol of old age and life's natural completion, counseling acceptance and joy rather than sorrow in the face of this decline.

Mondamin, the 'friend of man,' challenges Hiawatha to single combat in the glow of evening. In the 'purple twilight' of the setting sun (i.e., in the western land) there now ensues the mythological struggle with the god who has sprung out of the unconscious.
The setting sun's purple twilight frames the mythological combat between Hiawatha and the unconscious-derived god Mondamin, positioning sunset as the liminal space in which ego confronts transformative archetypal forces.

If you need to access more of the Lover, for example, and sunsets don't interest you, go out and really look at a sunset. Act as if you appreciate it. Notice the colors. Force yourself to see the beauty.
Moore employs the sunset as a practical instrument for activating the Lover archetype, treating aesthetic attention to its colors as a discipline for accessing emotional and sensory depth.

The night of spirit, the sinking of consciousness, the 'dark night of the soul,' is a necessary movement in the rhythm of light and darkness. Included in solar sensibility… is this downward movement toward twilight of understanding.
Moore's Ficinian solar psychology identifies the movement toward twilight—of which sunset is the emblematic moment—as a psychologically necessary descent within the broader rhythm of solar consciousness.

He did so and remained hidden until sunset. Then he came out and presented himself to the king, and said the sun has set and you didn't find me.
In this fairy-tale context analyzed by von Franz, sunset marks the boundary of the king's power to seek and find, functioning as a temporal threshold with implicit chthonic significance.

a solitary bull rolling in the dust against the bloodred sunset like an animal in sacrificial torment. The blood red dust blew down out of the sun.
McCarthy's literary image, cited in the context of Hillman's work, deploys the bloodred sunset as a figure of sacrificial violence and liminal passage, resonant with depth-psychological themes of the dying-sun archetype.

the precinct was opened only at the beginning of the Choes, after sunset on that first day (for the Greek day, like the Jewish, began at sunset).
Padel notes the cultural-calendrical significance of sunset as the threshold inaugurating the most polluted day of the Athenian festival year, reflecting a broader archaic understanding of sunset as a liminal and chthonically charged moment.
