The puella aetema would be the ‘eternal daughter’ type of woman, one who is unconsciously identified with the anima of the father. Such a woman lives, as does the Jung man of the puer type, in an archetypal role. She is a Kore, the numinous anima mundi, a goddess of light.
Von Franz establishes the puella aeterna as the precise feminine parallel to the puer aeternus: a woman identified with the father’s anima who lives an archetypal Kore-existence, illustrated by figures such as Greta Garbo and Brigitte Bardot.
