NERO was but sixteen years old when he began to reign. For two or three years he was under the influence of his tutor, SENECA, the author, and BURRHUS, the Praefect of the Praetorian Guard, and his government was during this period the most respectable of any since the time of Augustus. His masters kept the young Emperor amused, and removed from the cares of state. But he soon became infatuated with an unscrupulous woman, POPPAEA SABINA, for whom he neglected and finally killed his wife, Octavia. It would be useless to follow in detail the crimes of Nero from this time. A freedman, TIGELLINUS, became his adviser, and was the real ruler of the Empire. He encouraged his master in all his vices and wickedness. Poppaea died from a kick administered by Nero in anger; Burrhus was disposed of; Agrippina, and Britannicus, the true heir to the throne, were murdered. The wealthy were plundered, and the feelings of his subjects outraged in every conceivable manner. The Emperor appeared in public, contending first as a musician, and afterwards in the sports of the circus. The great fire of 18 July, 64, which destroyed a large part of the city, was ascribed to him, but without sufficient evidence; and the stories of his conduct during the conflagration are doubtless pure fictions. It was necessary, however, to fix the guilt on some one; so the CHRISTIANS, then a small sect, made up chiefly of the poorer people, were accused of the crime, and persecuted without mercy. They were often enclosed in fagots covered with pitch, and burned alive. In rebuilding Rome, Nero took every precaution against the recurrence of a conflagration. Broad regular streets replaced the narrow winding alleys. The new houses were limited in height, built partly of hard stone, and protected by open spaces and colonnades. The water supply was also carefully regulated. In addition to rebuilding the city, Nero gratified his love for the magnificent by erecting a splendid palace, called the GOLDEN HOUSE. Its walls were adorned with gold, precious stones, and masterpieces of art from Greece. The grounds around were marvellous in their meadows, lakes, groves, and distant views. In front was a colossal statue of Nero himself, one hundred and ten feet high.
