In the manufacture of arms, the steel of Poitou had already become celebrated. John, monk of Marmoustier, who lived in the middle of the twelfth century, in describing the knighting of Geoffry, duke of Normandy, tells us that he had a lance of ash, armed with a head of Poitou steel. Malmesbury distinguishes also Lorraine. "At the siege of Antioch," he says, "Godfrey of Bouillon, with a Lorrainian sword, cut asunder a Turk who had demanded single combat, so that one half of the man lay panting on the ground, while the other half was carried off by the horse at full speed; so firmly did the unbeliever keep his seat. Another also, who attacked him, he clave asunder from the neck to the groin; nor did the dreadful stroke stop here, but cut entirely through the saddle and the backbone of the horse." Hungary had at a very early period enjoyed a celebrity for its weapon manufacture. Charlemagne, writing to Offa of Mercia, offering him presents for his churches, adds: "And for your own acceptance I send a belt, a Hungarian sword, and two silk mantles[229]." The method of hardening steel, in the eleventh and twelfth centuries, by immersion, when red hot, in cold water, may be seen in Theophilus Presbyter, lib. iii. cap. 19. The FLAGS AND STANDARDS in use during this period were the prince's standards, the banner, the pennon, and the small lance-flag or streamer. The consecrated standard of William I., bestowed by the Pope, appears to be represented on the ninth plate of the Bayeux tapestry, where it is figured of a square form and ensigned with a cross. It was carried near the person of William throughout the day by the knight Toustain: "Turstinus, filius Rollonis _vexillum Normannorum_ portavit[230]." "Et quant li Dus tournout, tournout; E quant arestout, arestout."--_Wace_, l. 13,807. It was also used to indicate any danger into which the leader might have fallen. Thus, when Philip Augustus was unhorsed at the battle of Bovines, Rigord tells us that his standard-bearer signified the king's peril by depressing the Royal Standard several times over the spot. The Dragon-standard, of which we have seen some examples in our first division, is still found among the Germans and the English. We have already observed its exact form in the pictures of Harold in the Bayeux tapestry. It accompanied the hosts of Richard Cœur-de-Lion. Richard of Devizes, in recording the attack upon the "Griffones" at Messina, says: "The king of England proceeded in arms: the terrible standard of the Dragon is borne in front; while, behind the king, the sound of the trumpet excites the army[231]." Hoveden, under date 1191, tells us that Richard "delivered _his Dragon_ (_Draconem suum_) to be borne by Peter de Pratellis." Guillaume le Breton, in the _Philippidos_, gives to the Emperor Otho a standard formed of a dragon and an eagle.
