The making of Roman Chain

You may know it as a Roman Chain, an Etruscan Chain or any one of the ancient names, largely forgotten, once borne by this noble construction. Whatever you wish to call it is, I feel, better than the currently popular moniker of the "Loop-in-Loop" chain. I feel that this is a name devoid of all respect not to mention the wonder which this beautiful expression of the Goldsmith's craft can instill. Based on a deceptively simple pattern, this little wonder was produced by almost every civilization which ever practiced the art of Goldsmithing.
