Another contrasting accessory is the so-called Zoninus collar, dating to the fourth or fifth century a.d., and today displayed at the Baths of Diocletian in Rome. Roughly wrought from iron, it dangled a large—presumably irritating and painful—pendant, of the sort of that people today use to identify lost dogs. The inscription informed any stranger who encountered the wearer on his or her own that this person was a runaway. It promised a reward of one gold coin (solidus) for their return.
