Chthonic deities are those associated with the underworld in mythological traditions, representing the forces of death, fertility, and the earth. Prominent figures include Hades from Greek mythology and Osiris from Egyptian lore. These gods often preside over the souls of the deceased and govern the afterlife, embodying both the feared and revered aspects of death. Their narratives frequently reflect themes of rebirth, indicating that death is a natural cycle leading to new life. Chthonic deities, thus, occupy a nuanced space in mythology, representing the interplay between life, death, and renewal.
