We see, then, that the amentum was known throughout Greece and Italy, in Spain and Gaul, in Central Europe, in Denmark, and Ireland. The light javelin to which it belongs is the weapon of the less highly civilized peoples. It is a weapon of the chase and of the common people, but it plays little part in the heavily-equipped citizen armies of Greece and Rome. In both lands it comes into prominence with the organization of light-armed troops, and then chiefly as the weapon of subject states and mercenaries. Hence we are forced to the conclusion that the amentum was the invention of the tribes of Central Europe, and in the course of their wanderings was carried throughout the southern and western portions of the Continent.

The fixed amentum does not appear to be known outside Europe, but somewhat similar contrivances exist to-day among savage tribes. Such is the ounep used by the people of New Caledonia and the New Hebrides. It is a thickish cord, 6 or 8 inches long, with a loop at one end and a knot at the other. The spears are 9 to 12 feet long, with a slight projection just behind the centre of gravity, behind which the cord is placed and twisted over the knot in such a way as to untie as the spear is thrown, remaining itself in the thrower’s hand. Examples of it can be seen in the Ethnographical Gallery of the British Museum, and our illustration is taken from a drawing exhibited there (Fig. [95]). A combination of this thong with the throwing-stick is found in New Zealand. The throwing-stick is by far the commonest contrivance for increasing the throw of a spear. It is widely used in Australia, Melanesia, Central America, and among the Eskimos, but is unknown in Europe, although throwing-sticks made of bone appear to have been used by Palaeolithic man in France.

The working of the amentum can be easily understood from our illustration. In preparing for an overhand throw the spear rests on the web between the thumb and fingers, but is really held by the two fingers inserted in the loop and projecting above the shaft. At the moment of throw the position is reversed; the pull on the amentum gives a half-turn to the shaft, and the javelin is held only by the amentum, the fingers being below the shaft. The action of the amentum is similar to that of the rifling of a gun. By imparting a rotatory movement to the missile it not only helps it to keep its direction but also increases its carry and penetrating power. The carry is further increased by the additional leverage given to the thrower’s arm. It is obvious that, as Philostratus points out,[[603]] length of finger was a considerable advantage to a javelin thrower.

The effect of the amentum on a light javelin has been demonstrated by practical experiments carried out by General Reffye for the Emperor Napoleon. It was found that a javelin which could only be thrown 20 metres by hand could, after a little practice, be thrown 80 metres, with the help of an amentum. Jüthner further records that an inexperienced thrower increased his throw from 25 to 65 metres by its use. The meaning of these figures can be realised from the fact that the record for javelin throwing made by Lemming, the winner at the Olympic games, was only 57·33 metres. It must be noted, however, that the javelin used in these games was a heavy one, weighing 800 grammes (about 2 lbs.), whereas the Greek javelin was very much lighter.[[604]]

The method of throwing the javelin is clearly shown on the vases. Two things are necessary: the amentum must be firmly fastened to the shaft, and the loop must be drawn tight by the fingers before the throw. The fastening of the amentum has been already described. On a red-figured psykter (Fig. [96]) we see the next stage in the preparation. A group of youths are preparing to practise under the supervision of a paidotribes and his assistant, while two other paidotribai are occupied with a pair of wrestlers. Two of the youths are testing the bindings; resting one end of the javelin on the ground, and holding it firm with their left hand, they pass the right hand along the shaft to see that the binding is secure. A third in the same position is passing his fingers through the loop, the lines of which have disappeared. A fourth has already inserted his fingers in the loop, and, raising the javelin breast-high, presses it forward with his left hand so as to draw the thong tight.

Two styles of javelin throwing can be distinguished, one in which the javelin is horizontal, the other in which it is pointed more or less upwards. The horizontal style is the practical style of war or the chase, the other the style of pure athletics. In the latter distance is the one and only object, and the thrower may take his time; in the former distance is only a secondary consideration compared with force and accuracy, and everything depends on rapidity of action. It is the difference between throwing in a cricket ball from the long field and throwing it in competition.
