Mythical magical artifact in Plato's Republic

The Ring of Gyges '/dʒ//aɪ/,/dʒ//iː//z/ (Γύγου Δακτύλιος, Gúgou Daktúlios, ) is a hypothetical magic ring mentioned by the philosopher Plato in Book 2 of his Republic (2:359a–2:360d). It grants its owner the power to become invisible at will. Using the ring as an example, this section of the Republic considers whether a rational, intelligent person who has no need to fear negative consequences for committing an injustice would nevertheless act justly.

Gyges of Lydia was a historical king, the founder of the Mermnad dynasty of Lydian kings. Various ancient works—the most well known being The Histories of Herodotus—gave different accounts of the circumstances of his acquisition of power. All, however, agree in asserting that he was originally a subordinate of King Candaules of Lydia, that he killed Candaules and seized the throne, and that he had either seduced Candaules' Queen before killing him, married her afterwards, or both. In the recounting of the myth by Glaucon (Plato's older brother, as a character of The Republic), an unnamed ancestor of Gyges was a shepherd in the service of the king of Lydia. After an earthquake, a chasm was revealed in a mountainside where he was feeding his flock. Entering the chasm, he discovered that it was in fact a tomb with a bronze horse containing a corpse, larger than that of a man, who wore a golden ring, which he then pocketed. He discovered that by adjusting the ring, he gained the power of invisibility. He then arranged to become one of the king's messengers as to the status of the flocks. Arriving at the palace, he used his new power of invisibility to seduce the queen, and with her help, murder the king, and become king of Lydia himself.

Cicero retells the story of Gyges in De Officiis to illustrate his thesis that a wise or good individual bases decisions on a fear of moral degradation as opposed to punishment or negative consequences. Cicero follows with a discussion of the role of thought experiments in philosophy. The hypothetical situation in question is complete immunity from punishment of the kind afforded to Gyges by his ring. J. R. R. Tolkien was familiar with Plato's myth and had possibly read part of the story's original text in Ancient Greek; the fable influenced his writing of his literary masterpiece The Lord of The Rings.
