Of a kindred nature was the reform of the calendar. The republican calendar, which strangely enough was still the old decemviral calendar - an imperfect adoption of the octaeteris that preceded Meton[117] - had by a combination of wretched mathematics and wretched administration come to anticipate the true time by 67 whole days, so that e. g. the festival of Flora was celebrated on the 11th July instead of the 28th April. Caesar finally removed this evil, and with the help of the Greek mathematician Sosigenes introduced the Italian farmer's year regulated according to the Egyptian calendar of Eudoxus, as well as a rational system of intercalation, into religious and official use; while at the same time the beginning of the year on the 1st March of the old calendar was abolished, and the date of the 1st January - fixed at first as the official term for changing the supreme magistrates and, in consequence of this, long since prevailing in civil life - was assumed also as the calendar-period for commencing the year. Both changes came into effect on the 1st January 709, and along with them the use of the Julian calendar so named after its author, which long after the fall of the monarchy of Caesar remained the regulative standard of the civilized world and in the main is so still. By way of explanation there was added in a detailed edict a star-calendar derived from the Egyptian astronomical observations and transferred - not indeed very skilfully - to Italy, which fixed the rising and setting of the stars named according to days of the calendar[118]. In this domain also the Roman and Greek worlds were thus placed on a par.

Such were the foundations of the Mediterranean monarchy of Caesar. For the second time in Rome the social question had reached a crisis, at which the antagonisms not only appeared to be, but actually were, in the form of their exhibition, insoluble and, in the form of their expression, irreconcilable. On the former occasion Rome had been saved by the fact that Italy was merged in Rome and Rome in Italy, and in the new enlarged and altered home those old antagonisms were not reconciled, but fell into abeyance.

Now Rome was once more saved by the fact that the countries of the Mediterranean were merged in it or became prepared for merging; the war between the Italian poor and rich, which in the old Italy could only end with the destruction of the nation, had no longer a battle-field or a meaning in the Italy of three continents. The Latin colonies closed the gap which threatened to swallow up the Roman community in the fifth century; the deeper chasm of the seventh century was filled by the Transalpine and transmarine colonizations of Gaius Gracchus and Caesar. For Rome alone history not merely performed miracles, but also repeated its miracles, and twice cured the internal crisis, which in the state itself was incurable, by regenerating the state. There was doubtless much corruption in this regeneration; as the union of Italy was accomplished over the ruins of the Samnite and Etruscan nations, so the Mediterranean monarchy built itself on the ruins of countless states and tribes once living and vigorous; but it was a corruption out of which sprang a fresh growth, part of which remains green at the present day. What was pulled down for the sake of the new building, was merely the secondary nationalities which had long since been marked out for destruction by the levelling hand of civilization.

Caesar, wherever he came forward as a destroyer, only carried out the pronounced verdict of historical development; but he protected the germs of culture, where and as he found them, in his own land as well as among the sister nation of the Hellenes. He saved and renewed the Roman type; and not only did he spare the Greek type, but with the same self-relying genius with which he accomplished the renewed foundation of Rome he undertook also the regeneration of the Hellenes, and resumed the interrupted work of the great Alexander, whose image, we may well believe, never was absent from Caesar's soul. He solved these two great tasks not merely side by side, but the one by means of the other. The two great essentials of humanity - general and individual development, or state and culture - once in embryo united in those old Graeco-Italians feeding their flocks in primeval simplicity far from the coasts and islands of the Mediterranean, had become dissevered when these were parted into Italians and Hellenes, and had thenceforth remained apart for many centuries. Now the descendant of the Trojan prince and the Latin king's daughter created out of a state without distinctive culture and a cosmopolitan civilization a new whole, in which state and culture again met together at the acme of human existence in the rich fulness of blessed maturity and worthily filled the sphere appropriate to such an union.

The outlines have thus been set forth, which Caesar drew for this work, according to which he laboured himself, and according to which posterity - for many centuries confined to the paths which this great man marked out - endeavoured to prosecute the work, if not with the intellect and energy, yet on the whole in accordance with the intentions, of the illustrious master. Little was finished; much even was merely begun. Whether the plan was complete, those who venture to vie in thought with such a man may decide; we observe no material defect in what lies before us - every single stone of the building enough to make a man immortal, and yet all combining to form one harmonious whole. Caesar ruled as king of Rome for five years and a half, not half as long as Alexander; in the intervals of seven great campaigns, which allowed him to stay not more than fifteen months altogether[119] in the capital of his empire, he regulated the destinies of the world for the present and the future, from the establishment of the boundary-line between civilization and barbarism down to the removal of the pools of rain in the streets of the capital, and yet retained time and composure enough attentively to follow the prize-pieces in the theatre and to confer the chaplet on the victor with improvised verses.

The rapidity and self-precision with which the plan was executed prove that it had been long meditated thoroughly and all its parts settled in detail; but, even thus, they remain not much less wonderful than the plan itself. The outlines were laid down and thereby the new state was defined for all coming time; the boundless future alone could complete the structure. So far Caesar might say, that his aim was attained; and this was probably the meaning of the words which were sometimes heard to fall from him - that he had "lived enough". But precisely because the building was an endless one, the master as long as he lived restlessly added stone to stone, with always the same dexterity and always the same elasticity busy at his work, without ever overturning or postponing, just as if there were for him merely a to-day and no to-morrow. Thus he worked and created as never did any mortal before or after him; and as a worker and creator he still, after wellnigh two thousand years, lives in the memory of the nations - the first, and withal unique, Imperator Caesar.
