Note (return) — Chapter XXI

We now turn to the use of amulets among the Celts. Some of these were symbolic and intended to bring the wearer under the protection of the god whom they symbolised. As has been seen, a Celtic god had as his symbol a wheel, probably representing the sun, and numerous small wheel discs made of different materials have been found in Gaul and Britain.1135 These were evidently worn as amulets, while in other cases they were offered to river divinities, since many are met with in river beds or fords. Their use as protective amulets is shown by a stele representing a person wearing a necklace to which is attached one of these wheels. In Irish texts a Druid is called Mag Ruith, explained as magus rotarum, because he made his Druidical observations by wheels.1136 This may point to the use of such amulets in Ireland. A curious amulet, connected with the Druids, became famous in Roman times and is described by Pliny. This was the "serpents' egg," formed from the foam produced by serpents twining themselves together. The serpents threw the "egg" into the air, and he who sought it had to catch it in his cloak before it fell, and flee to a running stream, beyond which the serpents, like the witches pursuing Tam o' Shanter, could not follow him. This "egg" was believed to cause its owner to obtain access to kings or to gain lawsuits, and a Roman citizen was put to death in the reign of Claudius for bringing such an amulet into court. Pliny had seen this "egg." It was about the size of an apple, with a cartilaginous skin covered with discs.1137 Probably it was a fossil echinus, such as has been found in Gaulish tombs.1138 Such "eggs" were doubtless connected with the cult of the serpent, or some old myth of an egg produced by serpents may have been made use of to account for their formation. This is the more likely, as rings or beads of glass found in tumuli in Wales, Cornwall, and the Highlands are called "serpents' glass" (glain naidr), and are believed to be formed in the same way as the "egg." These, as well as old spindle-whorls called "adder stones" in the Highlands, are held to have magical virtues, e.g. against the bite of a serpent, and are highly prized by their owners.1139
