Attica is full of places unknown to most of its inhabitants. One of them is located in western Attica and specifically in Elefsina. So there are some rocks that create a cave. So this rock that stands there is called a sullen stone, and mythology mentions something that not many people know.
The rock, the cave, and the myth in Attica
This place in Elefsina was considered sacred. That’s because, according to tradition, Dimitra sat there to rest and mourn her daughter Persephone, who was snatched by Pluto. But what does the cave we mentioned have to do with it? The German archaeologist Otto Rubenzon, and not only he, supported the view that the “sullen stone” consisted of a series of three rocks showing the entrance of a cave. So this was considered to be one of the entrances to the underworld.
The three rocks were accompanied by three water sources, Anthia, Panthia, and Kallichronon. So there is the Plutonium, the temple in honor of Hades, which is considered to have been the passage to the Underworld.
It is a shallow cave with carved steps that lead to its interior. The dark niches and enigmatic fissures of the rock on the back walls of the cave led the ancient Elefsinians to regard them as passages to the Underworld, to the dark world of shadows, Hades.
Thus, the cave was characterized as Plutonium, associated with the worship of the God of the Underworld, Pluto.

The reason for the archaeological site of Elefsina. And who doesn’t know the famous “Elefsinian Mysteries”? These were the great celebrations in spring, the month of and the autumn. In the initiation, they were excluded from the ranks of the culprits of murder, those who did not speak the Greek language. The mystics returned to their place morally improved, happy, with reduced fear of death and increased hope for a better life.
