At Hallstatt there was the _normal_ evolution from bronze swords and axes to iron swords and axes. Why, then, had Homer's men in his time not made this step, seeing that they were familiar with the use of iron? Why do they use bronze for swords and spears, iron for tools? The obvious answer is that they could temper bronze for military purposes much better than they could temper iron. Now Mr. Ridgeway quotes Polybius (ii. 30; ii. 33) for the truly execrable quality of the iron of the Celtic invaders of Italy as late as 225 B.C. Their swords were as bad as, or worse than, British bayonets; they _always_ "doubled up." "Their long iron swords were easily bent, and could only give one downward stroke with any effect; but after this the edges got so turned and the blades so bent that, unless they had time to straighten them with the foot against the ground, they could not deliver a second blow." [Footnote: _Early Age of Greece_, vol. i. 408.] If the heroes in Homer's time possessed iron as badly tempered as that of the Celts of 225 B.C., they had every reason to prefer, as they did, excellent bronze for all their military weapons, while reserving iron for pacific purposes. A woodcutter's axe might have any amount of weight and thickness of iron behind the edge; not so a sword blade or a spear point. [Footnote: Monsieur Salomon Reinach suggests to me that the story of Polybius may be a myth. Swords and spear-heads in graves are often found doubled up; possibly they are thus made dead, like the owner, and their spirits are thus set free to be of use to his spirit. Finding doubled up iron swords in Celtic graves, the Romans, M. Beinach suggests, may have explained their useless condition by the theory that they doubled up in battle, leaving their owners easy victims, and this myth was accepted as fact by Polybius. But he was not addicted to myth, nor very remote from the events which he chronicles. Again, though bronze grave-weapons in our Museum are often doubled up, the myth is not told of the warriors of the age of bronze. We later give examples of the doubling up, in battle, of Scandinavian iron swords as late as 1000 A.D.] In the _Iliad_ we hear of swords breaking at the hilt in dealing a stroke at shield or helmet, a thing most incident to bronze swords, especially of the early type, with a thin bronze tang inserted in a hilt of wood, ivory, or amber, or with a slight shelf of the bronze hilt riveted with three nails on to the bronze blade.
