There are four legends concerning Prometheus.

According to the first, he was clamped to a rock in the Caucasus for betraying the secrets of the gods to men, and the gods sent eagles to feed on his liver, which was permanently renewed.

According to the second, Prometheus, goaded by the pain of the tearing beaks, pressed himself deeper and deeper into the rock until he became one with it.

According to the third, his treachery was forgotten in the course of years, forgotten by gods, the eagles, forgotten by himself.

According to the fourth, everyone grew weary of the meaningless affair. The gods grew weary, the eagles grew weary, the wound closed wearily.

There remained the inexplicable mass of rock. The legend tried to explain the inexplicable. As it came out of a substratum of truth it had in turn to end in the inexplicable.
