What was the eagle's name that ate Prometheus' liver?

In Greek mythology, Aethon ( "burning", "blazing" or "shining"), also known as "Eagle of the Caucasus", or "Eagle of Prometheus" is a giant eagle born from the monsters Typhon and Echidna.

It's one of the mythical creatures that appear in the legendary tales of ancient Greece. Gigantic in stature, it's famous for his role in punishing the Titan Prometheus.

Prometheus had been the benefactor of man after the Titanomachy. Having created humanity from clay, he had imbued it with skills and abilities taken from the Olympian gods prior to stealing the secret of fire from Hephaestus's workshop.

Having taught mankind how to get the best of sacrifices made to the gods, Zeus's wrath boiled over, resulting in punishment for the Titan.

Prometheus was thus chained to the immovable mountains of the Caucasus with unbreakable chains made by Hephaestus.

Then, as additional torture, Aethon eat feasted on his liver every day since it would regenerate every night. Prometheus was, of course, immortal, so he did not die when his liver was ripped out, but he would suffer perpetual pain due to the eagle's actions.

Prometheus' punishment lasted for many years. The Roman writer Hyginus, in Fables, put a time scale of 30,000 years until he was freed by Heracles, who had previously killed Aethon with poisoned arrows.
