In Roman mythology, the deity considered the queen of the underworld is **Proserpina**. She is often associated with the changing seasons and the cycle of life and death, representing both **fertility** and **despair**. Proserpina's story involves her abduction by **Pluto**, leading to her dual existence between the underworld and the earth, symbolizing the connection between life and death. Her narrative reflects the complexities of nature, loss, and the transformation inherent in the cycle of existence.
