Fourthly, Venatio, which was the fighting of wild beasts with one another, or with men called Bestiarii, who were either forced to the combat by way of punishment, as the primitive Christians were, or fought voluntarily, either from a natural ferocity of disposition, or induced by hire. An incredible number of animals of various kinds were brought from all quarters, at a prodigious expense, for the entertainment of the people. Pompey, in his second consulship, exhibited at once five hundred lions, which were all dispatched in five days; also eighteen elephants. Fifthly the representation of a horse and foot battle, with that of an encampment or a siege. Sixthly, the representation of a sea-fight (Naumachia), which was at first made in the Circus Maximus, but afterwards elsewhere. The combatants were usually captives or condemned malefactors, who fought to death, unless saved by the clemency of the emperor. If any thing unlucky happened at the games, they were renewed, and often more than once. [67] A meadow beyond the Tiber, in which an excavation was made, supplied with water from the river. [68] Julius Caesar was assisted by Sosigenes, an Egyptian philosopher, in correcting the calendar. For this purpose he introduced an additional day every fourth year, making February to consist of twenty-nine days instead of twenty-eight, and, of course, the whole year to consist of three hundred and sixty-six days. The fourth year was denominated Bissextile, or leap year, because the sixth day before the calends, or first of March, was reckoned twice. The Julian year was introduced throughout the Roman empire, and continued in general use till the year 1582. But the true correction was not six hours, but five hours, forty-nine minutes; hence the addition was too great by eleven minutes. This small fraction would amount in one hundred years to three-fourths of a day, and in a thousand years to more than seven days. It had, in fact, amounted, since the Julian correction, in 1582, to more than seven days. Pope Gregory XIII., therefore, again reformed the calendar, first bringing forward the year ten days, by reckoning the 5th of October the 15th, and then prescribing the rule which has gradually been adopted throughout Christendom, except in Russia, and the Greek church generally. [69] Principally Carthage and Corinth. [70] The Latus Clavus was a broad stripe of purple, on the front of the toga. Its width distinguished it from that of the knights, who wore it narrow. [71] The Suburra lay between the Celian and Esquiline hills. It was one of the most frequented quarters of Rome. [72] Bede, quoting Solinus, we believe, says that excellent pearls were found in the British seas, and that they were of all colours, but principally white. Eccl. Hist. b. i. c. 1.
