But the invention and frequent use of _extraordinary pains_ proceeded from the desire to extend and conceal the progress of despotism. In the condemnation of illustrious Romans the senate was always prepared to confound, at the will of their masters, the judicial and legislative powers. It was the duty of the governors to maintain the peace of their province by the arbitrary and rigid administration of justice; the freedom of the city evaporated in the extent of empire, and the Spanish malefactor, who claimed the privilege of a Roman, was elevated by the command of Galba on a fairer and more lofty cross. Occasional rescripts issued from the throne to decide the questions which, by their novelty or importance, appeared to surpass the authority and discernment of a proconsul. Transportation and beheading were reserved for honorable persons; meaner criminals were either hanged, or burned, or buried in the mines, or exposed to the wild beasts of the amphitheatre. Armed robbers were pursued and extirpated as the enemies of society; the driving away of horses or cattle was made a capital offence, but simple theft was uniformly considered as a mere civil and private injury. The degrees of guilt and the modes of punishment were too often determined by the discretion of the rulers, and the subject was left in ignorance of the legal danger which he might incur by every action of his life. A sin, a vice, a crime, are the objects of theology, ethics, and jurisprudence. Whenever their judgments agree, they corroborate each other; but as often as they differ a prudent legislator appreciates the guilt and punishment according to the measure of social injury. On this principle the most daring attack on the life and property of a private citizen is judged less atrocious than the crime of treason or rebellion, which invades the _majesty_ of the republic; the obsequious civilians unanimously pronounced that the republic is contained in the person of its chief; and the edge of the Julian law was sharpened by the incessant diligence of the emperors. The licentious commerce of the sexes may be tolerated as an impulse of nature, or forbidden as a source of disorder and corruption; but the fame, the fortunes, the family of the husband, are seriously injured by the adultery of the wife. The wisdom of Augustus, after curbing the freedom of revenge, applied to this domestic offence the animadversion of the laws; and the guilty parties, after the payment of heavy forfeitures and fines, were condemned to long or perpetual exile in two separate islands.
