The same famine of iron prevailed to a still greater extent in the Highlands, where it was even more valued, as the clans lived chiefly by hunting, and were in an almost constant state of feud. Hence the smith was a man of indispensable importance among the Highlanders, and the possession of a skilful armourer was greatly valued by the chiefs. The story is told of some delinquency having been committed by a Highland smith, on whom justice must be done; but as the chief could not dispense with the smith, he generously offered to hang two weavers in his stead! At length a great armourer arose in the Highlands, who was able to forge armour that would resist the best Sheffield arrow-heads, and to make swords that would vie with the best weapons of Toledo and Milan. This was the famous Andrea de Ferrara, whose swords still maintain their ancient reputation. This workman is supposed to have learnt his art in the Italian city after which he was called, and returned to practise it in secrecy among the Highland hills. Before him, no man in Great Britain is said to have known how to temper a sword in such a way as to bend so that the point should touch the hilt and spring back uninjured. The swords of Andrea de Ferrara did this, and were accordingly in great request; for it was of every importance to the warrior that his weapon should be strong and sharp without being unwieldy, and that it should not be liable to snap in the act of combat. This celebrated smith, whose personal identity[25] has become merged in the Andrea de Ferrara swords of his manufacture, pursued his craft in the Highlands, where he employed a number of skilled workmen in forging weapons, devoting his own time principally to giving them their required temper. He is said to have worked in a dark cellar, the better to enable him to perceive the effect of the heat upon the metal, and to watch the nicety of the operation of tempering, as well as possibly to serve as a screen to his secret method of working.[26] Long after Andrea de Ferrara's time, the Scotch swords were famous for their temper; Judge Marshal Fatten, who accompanied the Protector's expedition into Scotland in 1547, observing that "the Scots came with swords all broad and thin, of exceeding good temper, and universally so made to slice that I never saw none so good, so I think it hard to devise a better." The quality of the steel used for weapons of war was indeed of no less importance for the effectual defence of a country then than it is now. The courage of the attacking and defending forces being equal, the victory would necessarily rest with the party in possession of the best weapons.
