In Etruria on the other hand, while the nation stagnated and decayed in political nullity and indolent opulence, the theological monopoly of the nobility, stupid fatalism, wild and meaningless mysticism, the system of soothsaying and of mendicant prophecy gradually developed themselves, till they reached the height at which we afterwards find them.
In the sacerdotal system no comprehensive changes, so far as we know, took place. The more stringent enactments, that were made about 465 regarding the collection of the process-fines destined to defray the cost of public worship, point to an increase in the ritual budget of the state - a necessary result of the increase in the number of its gods and its temples. It has already been mentioned as one of the evil effects of the dissensions between the orders that an illegitimate influence began to be conceded to the colleges of men of lore, and that they were employed for the annulling of political acts[19] - a course by which on the one hand the faith of the people was shaken, and on the other hand the priests were permitted to exercise a very injurious influence on public affairs.
A complete revolution occurred during this epoch in the military system. The primitive Graeco-Italian military organization, which was probably based, like the Homeric, on the selection of the most distinguished and effective warriors - who ordinarily fought on horseback - to form a special vanguard, had in the later regal period been superseded by the legio - the old Dorian phalanx of hoplites, probably eight file deep[20]. This phalanx thenceforth undertook the chief burden of the battle, while the cavalry were stationed on the flanks, and, mounted or dismounted according to circumstances, were chiefly employed as a reserve. From this arrangement there were developed nearly at the same time the phalanx of sarrissae in Macedonia and the manipular arrangement in Italy, the former formed by closing and deepening, the latter by breaking up and multiplying, the ranks, in the first instance by the division of the old legio of 8400 into two legiones of 4200 men each. The old Doric phalanx had been wholly adapted to close combat with the sword and especially with the spear, and only an accessory and subordinate position in the order of battle was assigned to missile weapons. In the manipular legion the thrusting-lance was confined to the third division, and instead of it the first two were furnished with a new and peculiar Italian missile weapon, the pilum a square or round piece of wood, four and a half feet long, with a triangular or quadrangular iron point - which had been originally perhaps invented for the defence of the ramparts of the camp, but was soon transferred from the rear to the front ranks, and was hurled by the advancing line into the ranks of the enemy at a distance of from ten to twenty paces. At the same time the sword acquired far greater importance than the short knife of the phalangite could ever have had; for the volley of javelins was intended in the first instance merely to prepare the way for an attack sword in hand. While, moreover, the phalanx had, as if it were a single mighty lance, to be hurled at once upon the enemy, in the new Italian legion the smaller units, which existed also in the phalanx system but were in the order of battle firmly and indissolubly united, were tactically separated from each other. Not merely was the close square divided, as we have said, into two equally strong halves, but each of these was separated in the direction of its depth into the three divisions of the hastati, principes, and triarii, each of a moderate depth probably amounting in ordinary cases to only four files; and was broken up along the front into ten bands (manipuli), in such a way that between every two divisions and every two maniples there was left a perceptible interval. It was a mere continuation of the same process of individualizing, by which the collective mode of fighting was discouraged even in the diminished tactical unit and the single combat became prominent, as is evident from the (already mentioned) decisive part played by hand-to-hand encounters and combats with the sword. The system of entrenching the camp underwent also a peculiar development. The place where the army encamped, even were it only for a single night, was invariably provided with a regular circumvallation and as it were converted into a fortress. Little change took place on the other hand in the cavalry, which in the manipular legion retained the secondary part which it had occupied by the side of the phalanx. The system of officering the army also continued in the main unchanged; only now over each of the two legions of the regular army there were set just as many war-tribunes as had hitherto commanded the whole army, and the number of staff-officers was thus doubled. It was at this period probably that the clear line of demarcation became established between the subaltern officers, who as common soldiers had to gain their place at the head of the maniples by the sword and passed by regular promotion from the lower to the higher maniples, and the military tribunes placed at the head of whole legions - six to each - in whose case there was no regular promotion, and for whom men of the better class were usually taken. In this respect it must have become a matter of importance that, while previously the subaltern as well as the staff-officers had been uniformly nominated by the general, after 392 some of the latter posts were filled up through election by the burgesses[21]. Lastly, the old, fearfully strict, military discipline remained unaltered. Still, as formerly, the general was at liberty to behead any man serving in his camp, and to scourge with rods the staff-officer as well as the common soldier; nor were such punishments inflicted merely on account of common crimes, but also when an officer had allowed himself to deviate from the orders which he had received, or when a division had allowed itself to be surprised or had fled from the field of battle. On the other hand, the new military organization necessitated a far more serious and prolonged military training than the previous phalanx system, in which the solidity of the mass kept even the inexperienced in their ranks. If nevertheless no special soldier-class sprang up, but on the contrary the army still remained, as before, a burgess army, this object was chiefly attained by abandoning the former mode of ranking the soldiers according to property[22] and arranging them according to length of service. The Roman recruit now entered among the light-armed "skirmishers" (rorariii), who fought outside of the line and especially with stone slings, and he advanced from this step by step to the first and then to the second division, till at length the soldiers of long service and experience were associated together in the corps of the triarii, which was numerically the weakest but imparted its tone and spirit to the whole army.
The excellence of this military organization, which became the primary cause of the superior political position of the Roman community, chiefly depended on the three great military principles of maintaining a reserve, of combining the close and distant modes of fighting, and of combining the offensive and the defensive. The system of a reserve was already foreshadowed in the earlier employment of the cavalry, but it was now completely developed by the partition of the army into three divisions and the reservation of the flower of the veterans for the last and decisive shock. While the Hellenic phalanx had developed the close, and the Oriental squadrons of horse armed with bows and light missile spears the distant, modes of fighting respectively, the Roman combination of the heavy javelin with the sword produced results similar, as has justly been remarked, to those attained in modern warfare by the introduction of bayonet-muskets; the volley of javelins prepared the way for the sword encounter, exactly in the same way as a volley of musketry now precedes a charge with the bayonet. Lastly, the elaborate system of encampment allowed the Romans to combine the advantages of defensive and offensive war and to decline or give battle according to circumstances, and in the latter case to fight under the ramparts of their camp just as under the walls of a fortress - the Roman, says a Roman proverb, conquers by sitting still.
