The traditional reformer, Servius Tullius, found the knights of Rome divided into three centuries of horsemen, each of which, in consequence of the accession to its numbers made by the last king, contained within itself two centuries, a first and a second. The old citizens, anxious in all things to keep up the old form of the state, had then prevented what were really six centuries from being acknowledged as such in name; but the present change extended to the name as well as the reality; and the three double centuries of the Ramnes, Tities, and Luceres, became now the six votes (_sex suffragia_) of the new united assembly. To these, which contained all the members of the houses, there were now added twelve new centuries of knights,[14] formed, as usual in the Greek states, from the richest members of the community, continuing, like the centuries below them, to belong to the thirty tribes of the commons. _Classes of Foot-soldiers_ It remained to organise the foot-soldiers of the state. Accordingly, all those of the commons whose property was sufficient to qualify them for serving even in the hindmost ranks of the phalanx, were divided into four classes. Of these the first class contained all whose property amounted to one hundred and fifty thousand pounds’ weight of copper. The soldiers of this class were required to provide themselves with the complete arms used in the front ranks of the phalanx; the greaves, the coat of mail, the helmet, and the round shield, all of brass; the sword, and the peculiar weapon of the heavy-armed infantry, the long pike. And as these were to bear the brunt of every battle, and were the flower of the state’s soldiers, so their weight in the great military assembly was to be in proportion; they formed eighty centuries; forty of younger men, between the ages of fifteen and forty-five years complete; and forty of elders, between forty-five and sixty: the first to serve in the field, the second to defend the city. The second class contained those whose property fell short of 100,000 pounds of copper, and exceeded or amounted to 75,000 pounds. They formed twenty centuries, ten of younger men, and ten of elders; and they were allowed to dispense with the coat of mail, and to bear the large oblong wooden shield called scutum, instead of the round brazen shield, clipeus, of the first ranks of the phalanx. The third class contained a like number of centuries, equally divided into those of the younger men and elders; its qualification was property between 50,000 pounds of copper, and 75,000 pounds; and the soldiers of this class were allowed to lay aside the greaves as well as the coat of mail. The fourth class again contained twenty centuries; the lowest point of its qualification was 25,000 pounds of copper, and its soldiers were required to provide no defensive armour, but to go to battle merely with the pike and a javelin. These four classes composed the phalanx;
