married a woman two days after her divorce from her first husband; Caesar pronounced the marriage void. [Sidenote: B.C. 45-44.] Law reforms went on. Caesar appointed a commission to examine the huge mass of precedents, reduce them to principles, and form a Digest. He called in Marcus Varro's help to form libraries in the great towns. He encouraged physicians and men of science to settle in Rome, by offering them the freedom of the city. To maintain the free population of Italy, he required the planters and farmers to employ a fixed proportion of free laborers on their estates. He put an end to the pleasant tours of senators at the expense of the provinces; their proper place was Italy, and he allowed them to go abroad only when they were in office or in the service of the governors. He formed large engineering plans, a plan to drain the Pontine marshes and the Fucine lake, a plan to form a new channel for the Tiber, another to improve the roads, another to cut the Isthmus of Corinth. These were his employments during the few months of life which were left to him after the close of the war. His health was growing visibly weaker, but his superhuman energy remained unimpaired. He was even meditating and was making preparation for a last campaign. The authority of Rome on the eastern frontier had not recovered from the effects of the destruction of the army of Crassus. The Parthians were insolent and aggressive. Caesar had determined to go in person to bring them to their senses as soon as he could leave Rome. Partly, it was said that he felt his life would be safer with the troops; partly, he desired to leave the administration free from his overpowering presence, that it might learn to go alone; partly and chiefly, he wished to spend such time as might remain to him where he could do most service to his country. But he was growing weary of the thankless burden. He was heard often to say that he had lived long enough. Men of high nature do not find the task of governing their fellow-creatures particularly delightful.
