While she was speaking the Emperor could not take his eyes from her. He watched each rhythmic gesture, each word as it fell from her exquisite lips. "What an adorable mistress she would be!" he thought, as he breathed the perfume of her hair. And, feeling that she had conquered him, that he was ready to do whatever she wished, Cleopatra had a thrill of delicious assurance--"In a little while I shall be queen!" On hearing that his sister, whom he believed he had got rid of, had arrived in Alexandria, and that Cæsar had sworn to restore her to power, Ptolemy XII had one of those fits of demented rage to which this offspring of a degenerate race was subject. "The traitress!" he cried, crushing with his foot a murrhine vase of exquisite beauty. "She has tricked me. This decision that she has had the impudence to proclaim is nothing but damnable treason!" And placing Achillas in command of his troops, he massacred the Roman guard. This was the beginning of a war which was to last two years. With all the strength of the Republic behind him it was obvious that Cæsar would win; but at the outset the insurrections and riots, with which his soldiers were not in the habit of dealing, were hard to handle. Rather than continually encounter these street brawls, where the odds were often against him, Cleopatra's champion decided it was wiser to shut himself and his garrison up behind the walls of the Bruchium; this could, in an emergency, be used as a fort, where he could hold siege while awaiting the arrival of his army.
