The concept of a single "goddess of all goddesses" is complex and depends heavily on the specific mythology or religious tradition you're looking at. There isn't a universally accepted figure that perfectly fits that description. However, here are a few contenders and why they might be considered:
* The Great Goddess: In some neopagan and feminist spiritualities, the "Great Goddess" is seen as the supreme deity, encompassing all other goddesses within her. She represents the feminine divine and the source of all creation. This is more of a theological concept than a figure found in ancient mythologies.
* Gaia/Terra (Greek/Roman): As the personification of the Earth, Gaia (Greek) or Terra (Roman) is arguably the mother of all gods and goddesses in her respective pantheon. She birthed Uranus (the sky) and Pontus (the sea), and from them came the Titans, who were the parents of the Olympian gods.
* Rhea (Greek): Rhea was the Titan mother of the Olympian gods, including Zeus, Poseidon, and Hades. She protected Zeus from his father Cronus, who was devouring his children. While she isn't the ultimate source of all existence like Gaia, she is a powerful mother figure who ensured the survival of the main Olympian gods.
* Aditi (Hindu): In Hinduism, Aditi is a Vedic goddess who is the mother of the gods (Devas). She is associated with freedom, boundlessness, and cosmic space.
* Isis (Egyptian): Isis was a powerful and important goddess in ancient Egypt, associated with magic, motherhood, protection, and healing. While not explicitly the "goddess of all goddesses," her influence was immense, and she was often seen as embodying the ideal feminine virtues and power.
It's important to remember that different cultures have different cosmologies and pantheons. The idea of a single supreme goddess may not fit within the framework of many polytheistic religions.
