When and how this new military organization of the Roman community came into existence, can only be conjectured. It presupposes the existence of the four regions; in other words, the Servian wall must have been erected before the reform took place. But the territory of the city must also have considerably exceeded its original limits, when it could furnish 8000 holders of full hides and as many who held lesser portions, or sons of such holders. We are not acquainted with the superficial extent of the normal Roman farm; but it is not possible to estimate it as under twenty -jugera-.(12) If we reckon as a minimum 10,000 full hides, this would imply a superficies of 190 square miles of arable land; and on this calculation, if we make a very moderate allowance for pasture, the space occupied by houses, and ground not capable of culture, the territory, at the period when this reform was carried out, must have had at least an extent of 420 square miles, probably an extent still more considerable. If we follow tradition, we must assume a number of 84,000 burgesses who were freeholders and capable of bearing arms; for such, we are told, were the numbers ascertained by Servius at the first census. A glance at the map, however, shows that this number must be fabulous; it is not even a genuine tradition, but a conjectural calculation, by which the 16,800 capable of bearing arms who constituted the normal strength of the infantry appeared to yield, on an average of five persons to each family, the number of 84,000 burgesses, and this number was confounded with that of those capable of bearing arms. But even according to the more moderate estimates laid down above, with a territory of some 16,000 hides containing a population of nearly 20,000 capable of bearing arms and at least three times that number of women, children, and old men, persons who had no land, and slaves, it is necessary to assume not merely that the region between the Tiber and Anio had been acquired, but that the Alban territory had also been conquered, before the Servian constitution was established; a result with which tradition agrees. What were the numerical proportions of patricians and plebeians originally in the army, cannot be ascertained.
Upon the whole it is plain that this Servian institution did not originate in a conflict between the orders. On the contrary, it bears the stamp of a reforming legislator like the constitutions of Lycurgus, Solon, and Zaleucus; and it has evidently been produced under Greek influence. Particular analogies may be deceptive, such as the coincidence noticed by the ancients that in Corinth also widows and orphans were charged with the provision of horses for the cavalry; but the adoption of the armour and arrangements of the Greek hoplite system was certainly no accidental coincidence. Now if we consider the fact that it was in the second century of the city that the Greek states in Lower Italy advanced from the pure clan-constitution to a modified one, which placed the preponderance in the hands of the landholders, we shall recognize in that movement the impulse which called forth in Rome the Servian reform—a change of constitution resting in the main on the same fundamental idea, and only directed into a somewhat different course by the strictly monarchical form of the Roman state.(13)

4. The enactments of the Twelve Tables respecting -usus- show clearly that they found the civil marriage already in existence. In like manner the high antiquity of the civil marriage is clearly evident from the fact that it, equally with the religious marriage, necessarily involved the marital power (v. The House-father and His Household), and only differed from the religious marriage as respected the manner in which that power was acquired. The religious marriage itself was held as the proprietary and legally necessary form of acquiring a wife; whereas, in the case of civil marriage, one of the general forms of acquiring property used on other occasions—delivery on the part of a person entitled to give away, or prescription—was requisite in order to lay the foundation of a valid marital power.
