Within the depth-psychology corpus, the egg occupies a position of remarkable symbolic density, functioning simultaneously as cosmogonic origin, alchemical vessel, self-symbol, and marker of psychic potential. Von Franz provides the most sustained treatment, tracking the egg across Vedic, Orphic, and Egyptian traditions to argue that it images the preformed totality of the Self in its unrealized, germinal state — a condition she links directly to the analytic moment of first genuine self-reflection. Jung approaches the egg through the lens of transformation symbolism and Egyptian theology, reading it as the self-generated container from which divine consciousness emerges, a motif folded into his broader account of the individuation process. Kerenyi and Campbell situate the cosmic egg within comparative mythology, identifying its near-universal distribution across Greek Orphic, Indian, Finnish, Japanese, and Egyptian cosmogonies. The alchemical tradition — represented by Abraham, Edinger, and the Jodorowsky commentary on the Tarot — treats the egg as the philosophical vessel wherein the four elements are enclosed and the opus of transformation is incubated. Hillman introduces a critical-historical dimension, exposing how embryological fantasy projected onto the egg shaped centuries of androcentric bias in natural philosophy. Kalsched reads the fairy-tale egg as the life principle in its wholeness, directly threatened by dismembering forces and requiring protective custody for resurrection to occur. The term thus spans cosmogony, alchemy, clinical symbolism, and the history of science — making it one of the most polyvalent figures in the entire library.
