The Astrology of the Puer Aeternus: Why Some People Never Grow Up
Why do some people seem to drift through life with endless potential but no concrete path? Why do they fear commitment, structure, and responsibility, yet dream of greatness and meaning? And why does adult life often feel like a betrayal of something magical they once knew?
In this blog post, I explore the archetype of the Puer Aeternus, the Eternal Child, through the lens of astrology, mythology, and psychology. This is the third episode in my series on shadow archetypes in the birth chart, and one of the most personally meaningful topics I’ve covered so far.
If you’ve ever felt like you’re "behind in life," stuck in a loop of ideas that never manifest, or struggling to fully enter adulthood, this one is for you.
What is the Puer Aeternus?
The term Puer Aeternus comes from Latin, meaning "eternal boy." First introduced by Carl Jung and later expanded by Marie-Louise von Franz, it refers to a psychological complex, an identity that is fixated on youth, freedom, potential, and the avoidance of limitation.
While often associated with men, this archetype shows up across genders. It’s a pattern that resists adulthood, not in age, but in integration. The Puer dreams of what could be but avoids what is. They chase inspiration but resist form. They want meaning without the mess.
In astrology, we find this pattern most clearly reflected in signs like Gemini, Sagittarius, Pisces, and sometimes Libra, the mutable signs, often associated with the Pages in tarot. These archetypes are full of movement, wonder, ideas, and adaptability, but when distorted, they can become scattered, non-committal, or inflated.

Why This Matters
We live in a time where many traditional rites of passage into adulthood have disappeared. The economic and social structures that once helped people build lives, homes, families, vocations, have become more fragmented or inaccessible. And in their place, we’ve seen a rise in fantasy, virtual reality, and overstimulation.
The modern world encourages us to stay in the realm of potential. But at some point, growth means choosing, grounding, and building.
Understanding the Puer Aeternus, and how it may be playing out in your chart, can bring insight into your relationship with responsibility, creativity, and the fear of limitation. It’s not about killing the child within you. It’s about giving that child a home to live in.
