30 (return) [ The poorest rank of soldiers possessed above forty pounds sterling, (Dionys. Halicarn. iv. 17,) a very high qualification at a time when money was so scarce, that an ounce of silver was equivalent to seventy pounds weight of brass. The populace, excluded by the ancient constitution, were indiscriminately admitted by Marius. See Sallust. de Bell. Jugurth. c. 91. * Note: On the uncertainty of all these estimates, and the difficulty of fixing the relative value of brass and silver, compare Niebuhr, vol. i. p. 473, &c. Eng. trans. p. 452. According to Niebuhr, the relative disproportion in value, between the two metals, arose, in a great degree from the abundance of brass or copper.—M. Compare also Dureau ‘de la Malle Economie Politique des Romains especially L. l. c. ix.—M. 1845.] 31 (return) [ Cæsar formed his legion Alauda of Gauls and strangers; but it was during the license of civil war; and after the victory, he gave them the freedom of the city for their reward.] 32 (return) [ See Vegetius, de Re Militari, l. i. c. 2—7.] That public virtue, which among the ancients was denominated patriotism, is derived from a strong sense of our own interest in the preservation and prosperity of the free government of which we are members. Such a sentiment, which had rendered the legions of the republic almost invincible, could make but a very feeble impression on the mercenary servants of a despotic prince; and it became necessary to supply that defect by other motives, of a different, but not less forcible nature—honor and religion. The peasant, or mechanic, imbibed the useful prejudice that he was advanced to the more dignified profession of arms, in which his rank and reputation would depend on his own valor; and that, although the prowess of a private soldier must often escape the notice of fame, his own behavior might sometimes confer glory or disgrace on the company, the legion, or even the army, to whose honors he was associated. On his first entrance into the service, an oath was administered to him with every circumstance of solemnity. He promised never to desert his standard, to submit his own will to the commands of his leaders, and to sacrifice his life for the safety of the emperor and the empire. 33 The attachment of the Roman troops to their standards was inspired by the united influence of religion and of honor. The golden eagle, which glittered in the front of the legion, was the object of their fondest devotion; nor was it esteemed less impious than it was ignominious, to abandon that sacred ensign in the hour of danger. 34 These motives, which derived their strength from the imagination, were enforced by fears and hopes of a more substantial kind.
