Here are some examples:
* Chang'e (Chinese mythology): A beautiful goddess who lives on the moon. She is often depicted as a princess or empress, associated with immortality and beauty.
* Diana (Roman mythology): The goddess of the hunt, the moon, and childbirth. She is also associated with wild animals and the wilderness, but her royal connections are strong, as she was the daughter of Jupiter, the king of the gods.
* Luna (Roman mythology): The personification of the moon itself. She is often depicted as a young woman or a goddess, representing the beauty and power of the moon.
* Selene (Greek mythology): The goddess of the moon, often depicted riding a silver chariot across the night sky. While not explicitly a princess, she is associated with royalty and the celestial realm.
* Tsukuyomi (Japanese mythology): The god of the moon, considered a powerful figure and often depicted as a ruler.
These are just a few examples, and there are many other myths and legends that feature moon-related figures with royal attributes.
While there may not be one singular "Moon Princess" legend, the recurring themes of beauty, power, and association with the celestial realm create a compelling archetype that has resonated across cultures and throughout history.
