The New Moon occupies a distinctive position in depth-psychological literature, functioning simultaneously as an astronomical datum, an archetypal threshold, and a symbol of coniunctio. Within the astrological-psychological tradition represented most fully by Greene and Sasportas, the New Moon is the Sun-Moon conjunction at birth, marking a personality configured toward subjective, inward orientation — a seed-moment before differentiation into light. Rudhyar extends this further, situating the New Moon within a systemic dualistic rhythm in which the Moon’s innermost orbital position corresponds to radical subjectivity. Von Franz, reading through alchemical texts, treats the New Moon as the moment of complete lunar evacuation that enables coniunctio — the soul passing from Moon to Sun in a sealed, hermetic interior. Jung, in Mysterium Coniunctionis, engages the Moon’s phases principally through their moral and psychological valences in Augustine and Paracelsus, where lunar darkness connotes folly, infection, and the unconscious underside of psychic life. Moore, following Ficino, situates awareness of lunar phases — including the dark and empty New Moon — as essential to the soul’s proper timing. The central tension running through this body of work is whether the New Moon represents a dangerous void, a fertile inception, or the alchemical precondition for transformative conjunction. All positions converge on one point: the phase is not neutral — it is charged with initiatory, psychological, and cosmological significance.
