Heracles Frees Prometheus

Heracles kills the eagle tormenting Prometheus and releases him, with Hesiod stressing Zeus's consent and Pseudo-Apollodorus adding Chiron and the olive bond.
Canonical narrative
Prometheus hangs in a punishment built to renew itself. The eagle descends and tears at an immortal liver. Night restores what the day has consumed, leaving the body ready for the same attack again. Hesiod makes the rhythm brutal and exact. The bonds are imposed by Zeus, but the end of the torment will also pass through Zeus's will.
Heracles reaches the sufferer with a bow. He kills the eagle and releases the son of Iapetus. In the Theogony, the action enlarges the glory of Zeus's mortal-born son, and Zeus allows it even while remembering the old contest of cunning. Liberation is therefore not a simple scene in which the younger hero defeats divine kingship. It is a negotiated change within the order that imposed the pain.
Pseudo-Apollodorus adds conditions. Chiron, wounded and longing for death, can stand as a mortal substitute for the immortal prisoner. Prometheus takes a bond of olive, preserving a sign of the sentence after the iron restraint ends. The later account then makes freedom immediately useful to Heracles: Prometheus advises him not to enter the Hesperidean garden himself, but to send Atlas for the apples while taking the sky.
The source difference matters. Hesiod gives eagle, renewed liver, heroic release, and Zeus's consent. The mythographer adds Chiron, the olive bond, and the transition to Atlas. Both make Heracles the physical liberator, but only the later telling spells out the exchange and turns Prometheus into the adviser for the next labor.
