John X., after trying for two years, in spite of his enemies, to maintain his regime from the Lateran, at last fell into their hands and was either strangled or starved to death in the dungeons of Castel San Angelo.
After the death of Guido, Marozia married his half-brother Ugo. The strange wedding took place in the Mausoleum of the Emperor Hadrian, where a bridal hall and nuptial chamber had been arranged and adorned for them.
From the fortress tomb of the Flavian Emperor, Ugo lorded it over the city of Rome, earning thereby the hatred of the people and especially of young Alberic, his ambitious step-son, the son of Marozia and Count Alberic of Spoleto.
The proud youth, forced one day to serve him as a page, with intentional awkwardness, splashed some water over him and in return received a blow. Mad with fury, Alberic rushed from Castel San Angelo and summoned the people to arms. The clarions sounded and the fortress tomb was surrounded by a blood-thirsty mob. In no time the actors changed places. Ugo escaped by means of a rope from a window in the castello and returned to Tuscany, leaving behind him his honor, his wife and his imperial crown, while the youth Alberic became master of Rome, cast Marozia into a prison in Castel San Angelo and kept his half-brother, John XI., a close prisoner in the Lateran.
But the imprisonment of Marozia, and her mysterious disappearance from the scenes of her former triumphs and baleful activity did not end the story of the woman regime in Rome.
There lived in a palace, built upon the ruins of nameless temples and sanctuaries, and embellished with all the barbarous splendor of Byzantine and Moorish arts, in the remote wilderness of Mount Aventine, a woman, who, in point of physical charms, ambition and daring had not her equal in Rome since the death of Marozia. Theodora the younger, as she is distinguished from her mother, the wife of Theophylactus, by contemporary chroniclers, was the younger sister of Marozia.
The boundless ambition of the latter had left nothing to achieve for the woman who had reached her thirtieth year when Alberic's revolution consigned her sister to a nameless doom.
Strange rumors concerning her were afloat in Rome. Strange things were whispered of her palace on Mount Aventine, where she assembled about her the nobility of the city and the surrounding castelli, and soon her court vied in point of sumptuousness and splendor with the most splendid and profligate of her time.
Her admirers numbered by thousands, and her exotic beauty caused new lovers to swell the ranks of the old with every day that passed down the never returning tide of time.
Some came openly and some came under the cover of night, heavily muffled and cloaked: spendthrifts, gamblers, gallants, men of fashion, officers of the Senator's Court, poets, philosophers, and the feudal lords of the Campagna.
