with him. He worked the iron with an almost incredible industry, rendering it flexible and tractable, and gave it all the forms and scrolls he wished, with a 'douceur et une gentillesse' which surprised and astonished all the smiths." The iron master Gaegart broke off fragments of the iron, and no member of the craft has ever been able to state with certainty just how the work was accomplished. Some think that it is cast, and then treated with the file; others say that it must have been executed by casting entire, with no soldering. In any case, the secret will never be divulged, for no one was in the confidence of Biscornette. Norman blacksmiths and workers in wrought iron were more plentiful than goldsmiths. They had, in those warlike times, more call for arms and the massive products of the forge than for gaudy jewels and table appointments. One of the doors of St. Alban's Abbey displays the skill of Norman smiths dealing with this stalwart form of ornament. Among special artists in iron whose names have survived is that of Jehan Tonquin, in 1388. Earlier than that, a cutler, Thomas de Fieuvillier, is mentioned, as having flourished about 1330. [Illustration: BISCORNETTE'S DOORS AT PARIS] Elaborate iron work is rare in Germany; the Germans always excelled rather in bronze than in the sterner metal. At St. Ursula's in Cologne there are iron floriated hinges, but the design and idea are French, and not native. One may usually recognize a difference between French and English wrought iron, for the French is often in detached pieces, not an outgrowth of the actual hinge itself, and when this is found in England, it indicates French work. Ornaments in iron were sometimes cut out of flat sheet metal, and then hammered into form. In stamping this flat work with embossed effect, the smith had to work while the iron was hot,--as Sancho Panza expressed it, "Praying to God and hammering away." Dies were made, after a time, into which the design could be beaten with less effort than in the original method. One of the quaintest of iron doors is at Krems, where the gate is made up of square sheets of iron, cut into rude pierced designs, giving scenes from the New Testament, and hammered up so as to be slightly embossed. The Guild of Blacksmiths in Florence flourished as early as the thirteenth century. It covered workers in many metals, copper, iron, brass, and pewter included. Among the rules of the Guild was one permitting members to work for ready money only. They were not allowed to advertise by street crying, and were fined if they did so. The Arms of the Guild was a pair of furnace tongs upon a
