      Archimedes esteemed mechanical inventions as greatly inferior in value to those speculations and demonstrations that convince the mind, and considered that his chief single work was discovering the mathematical relation between a sphere and a cylinder just containing it.

      Whether this discovery and the discovery of the hydrostatic principle just mentioned were inventions or not, depends, of course, on the meaning of the word invention. Within the meaning of the word as employed heretofore in this book, both seem to have been inventions. Each made a definite creation and each caused something to exist, the like of which had never existed before. Furthermore, the mental processes followed resemble very closely the conception and formulation of a religion or a theory, the conception and composing of a new piece of music, story or poem, the conception and developing of any new plan or scheme; the conception and embodying in material form of any mechanical device.

      It is not asserted, of course, that all inventions are on a dead level of equality, simply because they are inventions. Evidently there are degrees of excellence among inventions as among all other things.

      INVENTION IN ROME: ITS RISE AND FALL

      We have noted, up to a time approximately that of Archimedes, a continual succession of inventions of many kinds, that formed stepping-stones to civilization so large and plain, that we can see them even from this distance.

      We now come to a period lasting more than a thousand years, in the first half of which there was a gradually decreasing lack of inventiveness shown, and in the latter half a cessation almost complete.

      The nation that followed Greece as the dominant nation of the world was Rome. She became more truly a dominant nation than Greece ever was; but her civilization was built on that of Greece, and her success even in war and government was due largely to following where Greece had led. That Rome in her early days should have followed the methods of Greece was natural of course; for the two countries were close together, and the methods of Greece had brought success. The early religion of Rome was so like that of Greece that even to this day the conceptions of most of us regarding Zeus and Jupiter, Poseidon and Neptune, Aphrodite and Venus are apt to become confused.

      Like the Greeks, the Romans first were gathered in city-states that were governed by kings; and as with the Greeks, more republican forms were adopted later. In one important particular, the Roman practice diverged from the Greek, and that was in incorporating conquered states into the parent state, and granting their inhabitants the privileges of citizenship; instead of keeping them in the condition of mere subject states. The Roman system was somewhat like the system of provinces established by the Assyrians. It forms the basis of the "municipal system" of the free states of the present day, in which local self-government is carried on, under the paramount authority of the state.

      It may be pointed out here that the conception of such an idea and its successful development into an effective machine of government by the Romans constituted an invention; though in view of what had been done before by Assyria and Greece, it cannot be called a basic invention.

      The early Romans were very different in their mental characteristics from the Greeks; for they were stern, warlike, intensely practical, and possessed of an extraordinary talent for what we now call "team work." As a nation they were not so inventive as the Greeks; but the Roman, Cæsar, was the greatest military inventor who ever lived.

      As might be expected, their early endeavors pertained to war, and their first improvements were in warlike things. One improvement that was marked by considerable inventiveness was in changing the phalanx into the legion. The phalanx, the historian Botsford tells us, was "invented by the Spartans, probably in the eighth century B. C.," and consisted of an unbroken line of warriors, several ranks deep. The Thebans improved on this; and from the Theban, Philip developed the Macedonian phalanx with which Alexander fought his way through Asia. The Romans under Servius Tullius developed this into the Roman phalanx, which was different only in detail. The essential characteristic of the phalanx was strength. This was gained by the close support given by each man to his neighbor, the personal strength of each man and the trained co-operation of all. A tremendous blow was given to an enemy's line when a phalanx struck it.

      In the early wars among the hills of Italy, the Romans found the phalanx too rigid for such uneven country; and it was in endeavoring to invent a substitute that they finally developed the legion. This machine was much more flexible, the individual soldiers had more room for their movements, and yet the machine seemed to possess the necessary rigidity when the shock of impact came. The heavy infantry was in three lines, and each line was divided into ten companies, or "maniples." The burden of the first attack was borne by the first line. If unsuccessful, the first line withdrew through gaps in the second line, and the second line took up the task; – and then the third, composed of the most seasoned troops. The attack usually began with the hurling of javelins, and was followed at once by an assault with the Roman strong short swords.

      Now the legion was just as truly an invented machine as a steam engine is; and it had a greater influence on history than the steam engine has ever had thus far. It was by means of their legions that the Romans passed outside of the walls of Rome, and conquered all of Italy. It was by means of their legions that the Romans conquered all the coast peoples that bordered the Mediterranean Sea, subdued Gaul, Europe and Egypt and Asia, and became the greatest masters of the world that the world has ever seen.

      The first war of the Romans that history calls great was their war against the splendid and wealthy city of Carthage, situated on the opposite side of the Mediterranean, inhabited by descendants of the Phœnicians. They were an aggressive and energetic people, but only commercially. They were not of the warlike cast, and delegated the work of national defense to hired soldiers and sailors. They had one great advantage over the Romans in the possession of an excellent navy.

      The Romans resolved to create a navy. With characteristic energy and practical ability, they devoted themselves at once to both the acquisition of the personnel and the material, and the adequate training of the crews. It is stated that within two months from the time of starting, Rome possessed a hundred quinqueremes, the largest galleys of those days, having five tiers of rowers; though they had had none when the war broke out. The first naval battle took place near the promontory of Mylæ. Naturally, the Romans were at a great disadvantage as compared with the experienced officers and sailors in the Carthaginian fleet; for though the Roman soldier was far better than the Carthaginian, the Roman sailor was inexperienced and unskilful. To remedy the difficulty, the Romans made a simple but brilliant invention. They provided each quinquereme with a "corvus," that consisted essentially of a drawbridge that could be lowered quickly, and that carried a sharp spike at its outer end; and then arranged a plan whereby each quinquereme should get alongside of a Carthaginian, drop the drawbridge at such a time that the spike would hold the outer end of the drawbridge in place on the Carthaginian deck, and Roman soldiers should then rush across the drawbridge and attack the inferior Carthaginian soldiers.

      Few more brilliant inventions have ever been made; few have been more successful and effective. The battle ended in a perfect victory for the Romans, and constituted the initial step in the subjugation of Carthage by Rome.

      There were three wars in all, called Punic Wars. The great Carthaginian General, Hannibal, invaded Italy by land in the Second War, and after a campaign marked with a high order of daring and ability, threatened Rome herself after a brilliant victory near Lake Trasimene. Another victory followed at Cannæ, but a decisive disaster later on the Metaurus River. So the Second War was won by Rome. But Carthage still existed, and menaced the commercial, naval and military dominance of Rome. Therefore war was brought about at last by Rome, and Carthage destroyed completely.

      The conduct of Rome toward Carthage cannot be justified on any grounds of any system of morality accepted at the present day; and yet it cannot reasonably СКАЧАТЬ
