chthón

Chthón, from the ancient Greek χθών (khthōn), means earth or ground and, by extension, the soil of the world. In classical usage, khthon designates both the surface of the earth and the subterranean realm. The term is the linguistic root of the English adjective chthonic, used to describe deities, powers, and cults associated with earth, fertility, and the dead, in contrast to the Olympian, celestial order.

In myth and religion, chthonic elements denote forces connected with the earth and the afterlife. Chthonic deities include Hades, Persephone, the Erinyes (Furies), and various earth-daimones. Cults honoring such powers often featured rites performed at tombs, caves, or subterranean shrines and could involve offerings linked to death and fertility cycles, distinct from offerings to the sky gods.

In modern usage, chthon refers to things related to the underworld or earth, with the term appearing as chthonic in theology, literature, psychoanalysis, and archaeology. The concept is commonly employed to explore primal, subterranean forces, hidden knowledge, or landscapes beneath the surface in both scholarly and fictional contexts.

The word also appears in classical poetry and philosophy as a term that foregrounds the earth as a counterpoint to the heavens, underscoring its enduring role in discussions of land, soil, and beneath-the-surface realms. See also chthonic, underworld, and earth in myth.
