Whatever of simplicity of character, and of gentleness and kindness of spirit she might have possessed in her earlier years, of course gradually disappeared under the influences of such a course of life as she now was leading. She was beautiful and fascinating still, but she began to grow selfish, heartless, and designing. Her little brother--he was but eleven years of age, it will be recollected, when Cæsar arranged the marriage between them--was an object of jealousy to her. He was now, of course, too young to take any actual share in the exercise of the royal power, or to interfere at all in his sister's plans or pleasures. But then he was growing older. In a few years he would be fifteen--which was the period of life fixed upon by Cæsar's arrangements, and, in fact, by the laws and usages of the Egyptian kingdom--when he was to come into possession of power as king, and as the husband of Cleopatra. Cleopatra was extremely unwilling that the change in her relations to him and to the government, which this period was to bring, should take place. Accordingly, just before the time arrived, she caused him to be poisoned. His death released her, as she had intended, from all restraints, and thereafter she continued to reign alone. During the remainder of her life, so far as the enjoyment of wealth and power, and of all other elements of external prosperity could go, Cleopatra's career was one of uninterrupted success. She had no conscientious scruples to interfere with the most full and unrestrained indulgence of every propensity of her heart, and the means of indulgence were before her in the most unlimited profusion. The only bar to her happiness was the impossibility of satisfying the impulses and passions of the human soul, when they once break over the bounds which the laws both of God and of nature ordain for restraining them.
