The following link goes to my recent blog article about Persephone as an archetype in context of the Persephone asteroid being conjunct Saturn in Scorpio right now, and having gone through a recent time period of also being conjunct the North Node of the Moon in Scorpio.  Persephone will continue to be with Saturn and the North Node of the Moon in Scorpio through the Summer, during which it will also be part of the Grand Water Trine that will occur involving Neptune in Pisces, Saturn in Scorpio, and Jupiter in Cancer.

As far as Jungians go, this particular article integrates some James Hillman, specifically his theory in "The Soul's Code."
