2. _Second Period. The Great Latin War_, B.C. 340.--The legion in B.C. 340 had almost entirely discarded the tactics of the phalanx. It was now drawn up in three, or perhaps we ought to say, in five lines. The soldiers of the first line, called Hastati, consisted of youths in the first bloom of manhood, distributed into 15 companies or maniples (_manipuli_), a moderate space being left between each. The maniple contained 60 privates, 2 centurions (_centuriones_), and a standard-bearer (_vexillarius_). The second line, the Principes, was composed of men in the full vigor of life, divided in like manner into 15 maniples, all heavily armed. The two lines of the Hastati and Principes taken together amounted to 30 maniples, and formed the Antepilani. The third line, the Triarii, composed of tried veterans, was also in 15 divisions, but each of these was triple, containing 3 maniples. In these triple maniples the veterans, or Triarii proper, formed the front ranks; immediately behind them stood the Rorarii, inferior in age and prowess, while the Accensi, or supernumeraries, less trustworthy than either, were posted in the extreme rear. 3. _Third Period. During the Wars of the younger Scipio._--Under ordinary circumstances four legions were levied yearly, two being assigned to each Consul. It must be observed that a regular consular army no longer consisted of Roman legions only, but, as Italy became gradually subjugated, the various states under the dominion of Rome were bound to furnish a contingent, and the number of allies usually exceeded that of the citizens. They were, however, kept perfectly distinct, both in the camp and in the battle-field. The men belonging to each legion were separated into four divisions. 1. 1000 of the youngest and poorest were set apart to form the Velites, the light-armed troops or skirmishers of the legion. 2. 1200 who came next in age (or who were of the same age with the preceding, but more wealthy) formed the Hastati. 3. 1200, consisting of those in the full vigor of manhood, formed the Principes. 4. 600 of the oldest and most experienced formed the Triarii. When the number of soldiers in the legion exceeded 4000, the first three divisions were increased proportionally, but the number of the Triarii remained always the same. The Hastati, Principes, and Triarii were each divided into 10 companies, called Maniples. The Velites were not divided into companies, but were distributed equally among the Hastati, Principes, and Triarii. Each maniple was subdivided into two centuries, commanded by a centurion. Each legion had six superior officers, called Tribuni Militum. The legion was also divided into 10 cohorts; and as the cohorts were all equal to each other, the strength of the cohort varied from time to time with the strength of the legion, and thus at different periods ranged between the limits of 300 and 600.
