But to return to Atossa. Her father Cyrus, who laid the foundation of the great Persian empire, was, for a hero and conqueror, tolerably considerate and just, and he desired, probably, to promote the welfare and happiness of his millions of subjects; but his son Cambyses, Atossa's brother, having been brought up in expectation of succeeding to vast wealth and power, and having been, as the sons of the wealthy and the powerful often are in all ages of the world, wholly neglected by his father during the early part of his life, and entirely unaccustomed to control, became a wild, reckless, proud, selfish, and ungovernable young man. His father was killed suddenly in battle, as has already been stated, and Cambyses succeeded him. Cambyses's career was short, desperate, and most tragical in its end.[A] In fact, he was one of the most savage, reckless, and abominable monsters that have ever lived. [Footnote A: His history in given in the first chapter of DARIUS THE GREAT.] It was the custom in those days for the Persian monarchs to have many wives, and, what is still more remarkable, whenever any monarch died, his successor inherited his predecessor's family as well as his throne. Cyrus had several children by his various wives. Cambyses and Smerdis were the only sons, but there were daughters, among whom Atossa was the most distinguished. The ladies of the court were accustomed to reside in different palaces, or in different suites of apartments in the same palace, so that they lived in a great measure isolated from each other. When Cambyses came to the throne, and thus entered into possession of his father's palaces, he saw and fell in love with one of his father's daughters. He wished to make her one of his wives. He was accustomed to the unrestricted indulgence of every appetite and passion, but he seems to have had some slight misgivings in regard to such a step as this. He consulted the Persian judges. They conferred upon the subject, and then replied that they had searched among the laws of the realm, and though they found no law allowing a man to marry his sister, they found many which authorized a Persian king to do whatever he pleased. Cambyses therefore added the princess to the number of his wives, and not long afterward he married another of his father's daughters in the same way. One of these princesses was Atossa. Cambyses invaded Egypt, and in the course of his mad career in that country he killed his brother Smerdis and one of his sisters, and at length was killed himself. Atossa escaped the dangers of this stormy and terrible reign, and returned safely to Susa after Cambyses's death.
