Rings Found in Mythology

Rings in Greek mythology, and writings about the origin of rings.

We not only find rings in the most ancient times, but we also trace them in mythology.
Fish, in antediluvian period, were intelligent, had fine musical perception and were even affectionate. Thus, in relation to Theseus, the Athenian prince: Minos happened to load Theseus with reproaches, especially on account of his birth; and told him, that, if he were the son of Neptune, he would have no difficulty in going to the bottom of the sea; and then threw a ring in to banter him. The Athenian prince plunged in, and might have been food for fishes, had they not, in the shape of dolphins, taken him upon their backs, as they had done Arion, and conveyed him to the palace of Amphitrite. It is not said whether she, as Neptune's wife, had a right to the jetsam, flotsam, and lagan, to the sweepings or stray jewelry of the ocean; but she was able to hand Theseus the ring, and also to give him a crown, which he presented to the ill-used lady Ariadne, and it was afterwards placed among the stars.

And, coupled with mythology, we have, according to the ancients, the origin of the ring. Jupiter, from revenge, caused Strength, Force and Vulcan to chain his cousin-german Prometheus to the frosty Caucasus, where a vulture, all the livelong day, banqueted his fill on the black viands of his hot liver. The god had sworn to keep Prometheus there (according to Hesiod) eternally; but other authors give only thirty thousand years as the limit. He who had punished did, for reasons, forgive; but as Jupiter had sworn to keep Prometheus bound for the space of time mentioned, he, in order not to violate his oath, commanded that Prometheus should always wear upon his finger an iron ring, to or in which should be fastened a small fragment of Caucasus, so that it might be true, in a certain sense, that Prometheus still continued bound to that rock. Thus, as we have said, came the idea of the first ring, and, we may add, the insertion of a stone.

While some writers, under this story, connect Prometheus with the first ring, Pliny still says that the inventor of it is not known, and observes that it was used by the Babylonians, Chaldeans, Persians and Greeks, although, as he thinks, the latter were unacquainted with it at the time of the Trojan war, as Homer does not mention it.

It has however been said that Dschemid, who made known the solar year, introduced the use of the ring.

Touching Pliny's notion of the antiquity of rings, there is, in Southey's "Commonplace Book," (second series,) the following quotation from "Treasurie of Auncient and Moderne Times," (1619:) "But the good olde man Plinie cannot overreach us with his idle arguments and conjectures, for we read in Genesis that Joseph, who lived above five hundred yeares before the warres of Troy, having expounded the dreame of Pharaoh, king of Egypt, was, by the sayde prince, made superintendent over his kingdom, and for his safer possession in that estate, he took off his ring from his hand and put it upon Joseph's hand.". . . "In Moses's time, which was more than foure hundred yeares before Troy warres, wee find rings to be then in use; for we reade that they were comprehended in the ornaments which Aaron the high priest should weare, and they of his posteritie afterward, as also it was avouched by Josephus. Whereby appeareth plainly, that the use of rings was much more ancient than Plinie reporteth them in his conjectures: but as he was a Pagan, and ignorant in sacred writings, so it is no marvell if these things went beyond his knowledge."
