Chthon is a term derived from ancient Greek mythology, referring to the underworld or the earth. It is often associated with deities and spirits that dwell beneath the surface, representing the hidden aspects of life and death. The word itself is linked to the Greek word "chthonios," meaning "of the earth" or "subterranean." In various mythologies, Chthon is connected to figures like Hades, the god of the underworld, and Persephone, his queen. These entities symbolize the cycle of life, death, and rebirth, emphasizing the importance of the earth and its mysteries in human existence.
