Melons grow in the shade of the leaves of a ground-growing runner, close-pressed against the earth... This motif of 'growing out of and on the earth' thus strongly emphasizes that for which his shadow was longing: to become caught in earthly reality.
Von Franz interprets the melon's botanical nature as a symbolic index of chthonic rootedness, reading it as the precise quality Descartes's disembodied rationalism lacked and that the unconscious was demanding he assimilate.
