Living as she did in an age where a morbid trend pervaded the world, where the approach of the Millennium, though no one of the present generation would see the day, was heralded as the End of Time; living as she did in the darkest epoch of Roman history, Theodora felt the utter inadequacy of her life, a hunger which nothing but power could assuage.

Slowly this desire began to grow and expand. She wished to wield her will, not only on men's emotions, but upon their lives as well. Perhaps even the death of Marozia, with its paralyzing influence over her soul, the captivity in the Lateran of her sister's son, and the hateful rule of Alberic, would not have brought matters to a focus, had not the appearance upon the stage of a woman, who, in point of beauty, spirit and daring bade fair to constitute a terrible rival, roused all the dormant passions in Theodora's soul and when Roxana openly boasted that she would wrest the power from the hands of her rival and rule in the Emperor's Tomb in spite of the Pontiff, of Alberic and Marozia's blood-kin, the soul of Theodora leaped to the challenge of the other woman and she craved for the conflict as she had never longed for anything in her life, save perchance, a love of which she had but possessed the base counterfeit.

No one knew whence Roxana had come, nor how long she had been in Rome, when an incident at San Lorenzo in Lucina had brought the two women face to face. Both, with their trains, had simultaneously arrived before the portals of the sanctuary when Roxana barred Theodora's way. Some mysterious instinct seemed to have informed each of the person and ambition of the other. For a moment they faced each other white to the lips. Then Roxana and her train had entered the church, and as she passed the other woman, a deadly challenge had flashed from her blue eyes into Theodora's dark orbs. The populace applauded Roxana's daring, and, in order to taunt her rival, she had established her court on desert Aventine, assembling about her the disgruntled lovers of Theodora and others, whom her disdain had driven to seek oblivion and revenge.

The land of Roxana's birth was shrouded in mystery. Some reported her from the icy regions of the North, others credited her with being the fugitive odalisque of some Eastern despot, a native of Kurdistan, the beauty and fire of whose women she possessed to a high degree.

Such was Roxana, who had challenged Theodora for the possession of the Emperor's Tomb.
