The large iron head mentioned by Polybius is an obtusely pointed pike-head with three or four barbs projecting backwards to a short distance from the head; behind the head is the neck, which, though long and slender, is capable of resisting a considerable amount of violent usage. This neck is about twenty inches in length, and at its base swells into a socket for the shaft, and encases the latter for a good portion of its length, being fitted with extreme care. The whole weapon was about six feet nine inches to seven feet in length, and may be described as one-third visible shaft, one-third shaft in iron socket, and the remainder a slender iron rod bearing a large head. It will readily be seen that, owing to the uncased shaft at the base, the centre of gravity would lie between the middle portion of the weapon and the head, thus adapting it for throwing purposes. The particular purpose of the pilum was to deprive an adversary of his shield. The method adopted was to approach within throwing distance and hurl the massive weapon at an opponent, who would naturally interpose his shield in defence; if the head crashed through the shield the object was accomplished, for owing to its form withdrawal was impossible, while the heavy shaft prevented any advance, and at the same time hindered retreat. To prevent the probability of either, however, the legionary with sword and shield promptly fell upon his embarrassed adversary, and there could be but one ending to such an unequal combat. For use at close quarters it was also equally efficacious, for, wielded with both hands like a mediæval pike, it could resist with ease the sword-cuts of the enemy; indeed Polybius tells us that the legionary received the sword-cuts of the enemy with calm confidence on his pilum, which resisted them with ease, while the adversary’s weapon was cut and hacked into the mere semblance of a strigil, or skin-scraper. This weapon was essentially Roman, and the troops wielding it were known as _pilani_. The cavalry carried a long and slender lance furnished with the _amentum_, a leather thong fitted nearly two-thirds of the length of the spear from the butt, being the centre of gravity of the shaft. This thong was of great use in propelling the spear when used as a javelin. The Roman dart was about three feet in length, and fitted with an extremely thin point about six inches long; upon striking any obstacle the point became so bent and distorted that it was of no use for hurling back again at the enemy. The light-armed troops also possessed a spear which was about four and a half feet in length. THE FRANKS
