In the Bronze Age several kinds of bronze daggers were made. The characteristic weapon of this period, however, was the leaf-shaped bronze sword. "No warlike weapon of any period is more graceful in form or more beautifully finished." This sword had a very thin edge on both sides running from hilt to point, and the handle was of bone, horn, or wood. The thinness of the edge seems to have been produced without the aid of hammer or file. The weapon was better fitted for stabbing and thrusting than for cutting with the edge. Bronze spear-points have been found, but throughout the Bronze Age arrow-heads were made of flint. There were also shields of bronze, held in the hand by a handle fastened to the center. The period of transition between the Bronze Age and the Iron Age is marked by an iron sword, which was similar in form to the leaf-shaped bronze sword. Homer, the great Greek bard who is supposed to have lived about a thousand years before the birth of Christ, in speaking of the wars of the Greeks, describes their weapons somewhat fully. They used a double-edged, bronze-bladed sword, the hilt and scabbard of which were adorned with gold and silver. In the combats of the Homeric age, however, the spear, lance, or javelin played the principal part; swords were used only for fighting at close range. Bows and arrows also were used. The only iron weapon specifically mentioned is the arrow-head. This was inserted in a split shaft, precisely like the flint arrow-heads of the early North American Indians and other modern savages. The defensive armor of the heroic age of Greece was entirely of bronze. It consisted of a helmet for the head, cuirass for the chest, greaves for the legs, and a shield. The bronze cuirass was often ornamented with gold. The shield was round or oval in shape, very large, and covered with hide. The Greeks of the later or historic age fought chiefly with long, heavy spears. Later the shield was reduced in size and the sword increased in length. The light-armed troops were furnished with a light javelin having a strap or thong fastened to the middle to assist in hurling. A linen corselet came into use instead of the heavy metal cuirass. The mounted troops were supplied with a longer sword, a javelin, and a short dagger.
