This decree shows that, as is proved by other texts, freedmen were sometimes accorded the privilege of wearing gold rings by special permission of the ruler or State, but all who could not obtain such special permission were punishable if they ventured to wear a gold ring, just as in countries where State orders are recognized and protected the wearing of such an order or of its ribbon by unauthorized persons is punishable in some way. The “right of regeneration” is more peculiar, as this refers to a legal fiction, by which it was assumed that some one of the ancestors of the freedman had been freeborn; hence, the quality of free-birth was only revived, not created, in the case of the descendant. This is, after all, not so unreasonable as it may seem to be, for the slaves, being generally prisoners of war, or else the descendants of citizens who had in some way lost their citizenship, could truly claim, in a majority of instances, that they came of freeborn stock. The image of Mars on a ring-stone was greatly favored by Roman soldiers. A good example of this style of ring is to be seen at the National Hungarian Museum in Budapest. The gem, a carnelian, is engraved with a figure of the god, with helmet and spear; his left hand rests on a shield bearing the Medusa’s head. The hoop is of silver. This ring was found in Bosnia and was donated to the museum in 1820.[30] An old Roman inscription mentions a guild of ring-makers (_conlegium anularium_),[31] and the denomination anularius even appears as a proper name of the engraver of a signet ring.[32] Near the Forum was a flight of steps designated _scalæ anulariæ_,[33] indicating either that ring engravers or vendors were to be found there, or that they had their shops or workshops in the neighborhood. Treating of the dictatorial conduct of the Procurator Verres, Cicero, in his violent, we might almost say virulent arraignment of him, were it not so well deserved, says that when Verres wished to have a ring made for himself he ordered that a goldsmith should be summoned to the Forum, publicly weighed out the gold for him, and commanded the man to set his bench down in the Forum and to make the ring in the presence of all.[34] Tacitus states in his Germania that the most valiant of the Cattæ, wore “like a fetter” an iron ring, which was a mark of infamy among the Germans. Only when a warrior had killed an enemy had he the right to divest himself of this ring. Whether this was a tribal usage, or only the sign of an obligation voluntarily assumed, must be left to conjecture. It is supposed to evidence that the slaves of the Germans wore iron rings, and that thus such rings were looked upon as badges of slavery.[35]
