The island, within the depth-psychological corpus, operates as one of the most semantically rich spatial symbols in the literature. Its primary register is isolation — a bounded, water-encircled realm that stands apart from the mainland of ordinary consciousness and social life. Von Franz establishes the foundational interpretive framework most explicitly: the island functions as a symbol of the unconscious psychic sphere, sheltering projections of archetypal content — the dead, enchantresses, sorceresses, and otherworldly figures. In this reading, Calypso and Circe on their respective islands are not merely mythological fixtures but personifications of captivating, potentially deadly unconscious forces. Von Franz further associates the island with a lost paradise, an idealized past state, the locus of the Self — an interpretive line that runs from the garden of the Hesperides through Celtic fairy islands to the Kronos-ruled northern isle where the golden age persists. Jung’s seminar commentary introduces the complementary motif of the ‘island of the dead,’ identifying it with the oceanic unconscious itself. Campbell extends the symbolic field toward the motif of the hidden soul — the external vital principle secreted on an island within an island, accessible only through heroic labor. The Homeric texts supply the mythic substrate throughout: Circe’s Aiaia, Kalypso’s unnamed isle, and Ithaca as longed-for homeland all map the island’s psychological range from entrapment through incubation to redemptive return. Plato’s Atlantis, an island civilization swallowed by the sea, anchors the tradition of the island as lost ideal polity.
