chthonian

As a chthonian power, she is worshipped at the Samothracian mysteries, and is closely connected with Demeter.

The chthonian aspect of the hero is further shown by his attribute the snake, and in many cases he appears under that form himself.

There is also indeed a glimmering of the dark background of the nether world, and the chthonian powers that might send up the Erinys to fulfil the curse of the wronged.

In earth's womb the old gods stir, Fierce chthonian dieties of old time.

It must be strange to die, surrounded by jackals at their chthonian litanies.
