Polybius, of Megalopolis in Greece, was born about 207 and died about 125 BCE. Polybius was well equipped by experience for the writing of history. He took an active part in the Achaean League before he was sent by the League as a hostage to Rome in 167 BCE. At Rome he was associated with the leading statesmen on terms of such intimacy that every opportunity was afforded him for studying the government and the people. After his release he entered upon extensive travels for the purpose of becoming acquainted with the places he was to describe. He was besides a close student of the various philosophical systems, and his wide reading in literature gave him powers of understanding and interpretation which warrant the description of him as one of the greatest of the Greek Historians. He conceived history as concerned mainly with politics and war; as dealing with observed facts to be reported: as under the necessity of explaining cause and effect instead of being content with a mere narration of events; and as an account of the interrelation of all states rather than a treatment of each as a separate unit. The first five books of the History we have complete: the rest is extant only in fragments. Beginning with a sketch of early Roman history, it covered in detail a period from the war with Hannibal, 219 BCE to the destruction of Carthage and of Corinth in 146 BCE.
(Polybius, carrying forward the work begun by Aristotle of examining
existing constitutions, arrives at the conclusion that the Roman
has more to commend it than any other yet tried. The principle
that wins his approval especially is the interdependence of its
several parts, the check system which controls while it allows
the exercise of power. His sketch is to be referred to the time
of the war with Hannibal just before 200 BCE.)
11. The three kinds of government that I spoke of above all shared in the control of the Roman state. And such fairness and propriety in all respects was shown in the use of these three elements for drawing up the constitution and in its subsequent administration that it was impossible even for a native to pronounce with certainty whether the whole system was aristocratic, democratic, or monarchical. This was indeed only natural. For if one fixed one's eyes on the power of the consuls, the constitution seemed completely monarchical and royal; if on that of the senate, it seemed again to be aristocratic; and when one looked at the power of the masses, it seemed clearly to be a democracy. The parts of the state falling under the control of each element were and with a few modifications still are as follows.
12. The consuls, previous to leading out their legions, exercise authority in Rome over all public affairs, since all the other magistrates except the tribune are under them and bound to obey them, and it is they who introduce embassies to the senate. Besides this, it is they who consult the senate on matters of urgency, they who carry out in detail the provisions of its decrees. Again, as concerns all affairs of state administered by the people it is their duty to take these under their charge, to summon assemblies, to introduce measures, and to preside over the execution of the popular decrees. As for preparation for war and the general conduct of operations in the field, here their power is almost uncontrolled; for they are empowered to make what demands they choose on the allies, to appoint military tribunes, to levy soldiers and select those who are fittest for service. They also have the right of inflicting, when on active service, punishment on any one under their command; and they are authorized to spend any sum they decide upon from the public funds, being accompanied by a quaestor who faithfully executes their instructions. So that if one looks at this part of the administration alone, one may reasonably pronounce the constitution to be a pure monarchy or kingship. I may remark that any changes in these matters or in others of which I am about to speak that may be made in present or future times do not in any way affect the truth of the views I here state.
13. To pass to the senate. In the first place it has the control of the treasury, all revenue and expenditure being regulated by it. For with the exception of payments made to the consuls, the quaestors are not allowed to disburse for any particular object without a decree of the senate. And even the item of expenditure which is far heavier and more important than any other-the outlay every five years by the censors on public works, whether constructions or repairs-is under the control of the senate, which makes a grant to the censors for the purpose. Similarly crimes committed in Italy which require a public investigation, such as treason, conspiracy, poisoning, and assassination, are under the jurisdiction of the senate, also if any private person or community in Italy is in need of arbitration or indeed claims damages or requires succour or protection, the senate attends to all such matters. It also occupies itself with the dispatch of all embassies sent to countries outside of Italy for the purpose either of settling differences, or of offering friendly advice, or indeed of imposing demands, or of receiving submission, or of declaring war; and in like manner with respect to embassies arriving in Rome it decides what reception and what answer should be given to them. All these matters are in the hands of the senate, nor have the people anything whatever to do with them. So that again to one residing in Rome during the absence of the consuls the constitution appears to be entirely aristocratic; and this is the conviction of many Greek states and many of the kings as the senate manages all business connected with them.
14. After this we are naturally inclined to ask what part in the constitution is left for the people, considering that the senate controls all the particular matters I mentioned, and, what is most important, manages all matters of revenue and expenditure, and considering that the consuls again have uncontrolled authority as regards armaments and operations in the field. But nevertheless there is a part and a very important part left for the people. For it is the people which alone has the right to confer honours and inflict punishment, the only bonds by which kingdoms and states and in a word human society in general are held together. For where the distinction between them is not sharply drawn both in theory and practice, there no undertaking can be properly administered,--as indeed we might expect when good and bad are held in exactly the same honor. The people then is the only court to decide matters of life and death; and even in cases where the penalty is money, if the sum to be assessed is sufficiently serious, and especially when the accused have held the higher magistracies. And in regard to this arrangement there is one point deserving special commendation and record. Men who are on trial for their lives at Rome, while sentence is in process of being voted,--if even only one of the tribes whose votes are needed to ratify the sentence has not voted,--have the privilege at Rome of openly departing and condemning themselves to a voluntary exile. Such men are safe at Naples or Praeneste or at Tibur, and at other towns with which this arrangement has been duly ratified on oath.
Again, it is the people who bestow offices of the deserving which are the most honorable rewards of virtue. It has also the absolute power of passing or repealing laws: and, most important of all, it is the people who deliberate on the question of peace or war. And when provisional terms are made for alliance, suspension of hostilities, or treaties, it is the people who ratify them or the reverse.
These considerations again would lead one to say that the chief power in the state was the people's, and that the constitution was a democracy.
15. Such, then, is the distribution of power between the several parts of the state. I must now show how each of these several parts can, when they choose, oppose or support each other.
The Consul, then, when he has started on an expedition with the powers I have described, is to all appearance absolute in the administration of the business at hand; still he has need of the support both of people and Senate; and, without them, is quite unable to bring the matter to a successful conclusion. For it is plain that he must have supplies sent to his legions from time to time; but without a decree of the Senate they can be supplied neither with grain nor clothes, nor pay, so that all the plans of a commander must be futile, if the Senate is resolved either to shrink from danger or hamper his plans. And again, whether a Consul shall bring any undertaking to a conclusion or not depends entirely on the Senate; for it has absolute authority at the end of a year to send another Consul to supersede him, or to continue the existing one in his command. Again, even to the successes of the generals, the Senate has the power to add distinction and glory, and on the other hand to obscure their merits and lower their credit. For these high achievements are brought in tangible form before the eyes of the citizens by what are called "triumphs." But in these triumphs the commanders cannot celebrate with proper pomp, or in some cases celebrate at all, unless the Senate concurs and grants the necessary money. As for the people, the Consuls are pre-eminently obliged to court their favor, however distant from home may be the field of their operations; for it is the people, as I have said before, that ratifies, or refuses to ratify, terms of peace and treaties; but most of all because when laying down their office they have to give an account of their administration before it. Therefore in no case is it safe for the Consuls to neglect either the Senate or the goodwill of the people.
16. As for the Senate, which possesses the immense power I have described, in the first place it is obliged in public affairs to take the multitude into account, and respect the wishes of the people; and it cannot put into execution the penalty for offenses against the republic, which are punishable
with death, unless the people first ratifies its decrees. The same is the case in matters which directly affect the senate itself, for if anyone introduces a law meant to deprive the senate of some of its traditional authority or to abolish the precedence and other distinctions of the senators or even to curtail them of their private fortunes, it is the people alone which has the power of passing or rejecting any such measure. And what is most important is that if a single one of the tribunes interposes, the senate is unable to decide finally about any matter, and cannot even meet and hold sittings; and here it is to be observed that the tribunes are always obliged to act as the people decree and to pay every attention to their wishes. Therefore for all these reasons the senate is afraid of the masses and must pay due attention to the popular will.
17. Similarly, again, the people must be submissive to the senate and respect its members both in public and in private. Through the whole of Italy a vast number of contracts, which it would not be easy to enumerate, are given out by the censors for the construction and repair of public buildings, and besides this there are many things which are farmed, such as navigable rivers, harbours, gardens, mines, lands, in fact everything that forms part of the Roman dominion. Now all these matters are undertaken by the people, and one may almost say that everyone is interested in these contracts and the work they involve. For certain people are the actual purchasers from the censors of the contracts, others are the partners of these first, others stand surety for them, others pledge their own fortunes to the state for this purpose. Now in all these matters the senate is supreme. It can grant extension of time; it can relieve the contractor if any accident occurs; and if the work proves to be absolutely impossible to carry out it can liberate him from his contract. There are in fact many ways in which the senate can either benefit or injure these who manage public property, as all these matters are referred to it. What is even more important is that the judges in most civil trials, whether public or private, are appointed from its members, where the action involves large interests. So that all citizens being at the mercy of the senate, and looking forward with alarm to the uncertainty of litigation, are very shy of obstructing or resisting its decision. Similarly everyone is reluctant to oppose the projects of the consuls as are generally and individually under their authority when in the field.
18. Such being power that each part has of hampering the others or co-operating with them, their union is adequate to all emergencies, so that it is impossible to find a better political system than this. For whenever the menace of some common danger from abroad compels them to act in concord and support each other, so great does the strength of the state become, that nothing which is requisite can be neglected as all are zealously competing in devising means of meeting the need of the hour, nor can any decision arrived at fail to be executed promptly, as all are co-operating both in public and in private to the accomplishment of the task they have set themselves; and consequently this peculiar form of constitution possesses an irresistible power of attaining every object upon which it is resolved. When again they are freed from external menace, and reap their success, and in the enjoyment of this prosperity are corrupted by flattery and idleness and was insolent and overbearing, as indeed happens often enough, it is then especially that we see the state providing itself a remedy for the evil from which it suffers. For when one part having grown out of proportion to others aims at supremacy and tends to become too predominant, it is evident that, as for the reasons above give none of the three is absolute, but the purpose of the one can be counterworked and thwarted by the others, none of them will excessively outgrow the others or treat them with contempt. All in fact remain in status quo, on the one hand, because any aggressive impulse is sure to be checked and from the outset each estate stands in dread of being interfered with by the others.
