But the trade with Hungary carried these daggers from Italy into Central Europe, and the Nordic inhabitants, both of the plain and of the mountains, were good customers. But being big men, with large hands and accustomed to meet their foes face to face, they demanded larger and larger daggers, and this demand was met, as such a demand always is, by an adequate supply. Thus we find these weapons, closely resembling those in use in the Mediterranean basin, especially in its western half, becoming increasingly common in Hungary, and growing to greater and greater dimensions. Plate IV. shows five daggers found in Hungary: the two first can be matched both in Greece and Italy and elsewhere in the Mediterranean region, the third in Italy only, the fourth in the northern part of that peninsula, while the fifth is rare outside Hungary, and I have only been able to find one parallel, from Bondo in the Grisons.[267] The increased size of the daggers, which in some cases had grown to enormous proportions, as may be seen in Plate V., made the weakness at the riveted joint more apparent. The Nordics, fighters above all else, paid much attention to their weapons, and they set themselves to discover some way to overcome this difficulty. This led, as we shall see, to the evolution of the leaf-shaped sword. During the bronze age there were several types of sword in use in various parts of the Old World. We have seen how the typical Mediterranean sword or long dirk developed by slow degrees in the west from the triangular copper daggers of Crete. In the Ægean and in Greek lands we find other types, which seem to be derived from swords of Asiatic origin, and which had an independent development in Mesopotamia or Egypt; some, too, may have been derived from the copper daggers of Cyprus. [Illustration: FIG. 11. BRONZE HILT OF LEAF-SHAPED SWORD.] But there is one type or group which stands apart from the others. In many examples the blade narrows rapidly near the butt, then expands slowly till it reaches its greatest breadth about two-thirds of the way down the blade; then it narrows more rapidly, then very quickly to the point. This gives a shape not unlike the leaf of the lanceolate plantain, a form not uncommon in other leaves; hence the name leaf-shaped sword. But many examples from this group, in other respects indistinguishable from those described, have sides which are nearly parallel, sometimes quite so. To these cases the term leaf-shaped is not so applicable. But the name is hallowed by a long tradition, and so it will be well to retain it for the whole group.
