About the time of the removal of the papacy to Avignon they were expelled from the city by the Church, but they returned on the invitation of the citizens who had risen against the papal legate. John XXII issued a diploma of investiture by the terms of which they were to hold Ferrara as a fief of the Church on payment of an annual tribute of ten thousand gold ducats. The Este now set themselves up as tyrants in Ferrara, and in spite of numerous wars maintained the dynasty for a great many years. This dominion was not, like that in many other Italian States, due to a lucky stroke on the part of an upstart, but it was ancient, hereditary, and firmly established.
It was due to a succession of remarkable princes, beginning with Aldobrandino, Lord of Ferrara, Modena, Rovigo, and Comacchio, that Ferrara succeeded in winning the important position she held at the beginning of the sixteenth century. Aldobrandino was followed by his brothers, Niccolò, from 1361 to 1388, and Alberto until 1393. After that his son Niccolò III, a powerful and bellicose man, ruled until the year 1441. As his legitimate children Ercole and Sigismondo were minors, he was succeeded by his natural son Lionello. This prince not only continued the work begun by his father, but also beautified Ferrara. In the year 1444 the great Alfonso of Naples gave him his daughter Maria as wife, and the Este thus entered into close relations with the royal house of Aragon. Lionello was intelligent and liberal, a patron of all the arts and sciences, a "prince of immortal name." In the year 1450 he was succeeded by his brother Borso, illegitimate like himself, as an effort was being made to displace the legitimate sons of Niccolò II.
Borso was one of the most magnificent princes of his age. Frederick II, when he stopped in Ferrara on his return from his coronation in Rome, made him Duke of Modena and Reggio, and Count of Rovigo and Comacchio, all of which territories belonged to the empire. The Este thereupon adopted for their arms, instead of the white eagle they had hitherto borne, the black eagle of the empire, to which were added the lilies of France, the use of which had been granted them by Charles VII. April 14, 1471, Paul VII in Rome created Borso Duke of Ferrara. Soon after this—May 27th—this celebrated prince died unmarried and childless.
He was succeeded by Ercole, the legitimate son of Niccolò II, the direct line of the Este thereby reacquiring the government of Ferrara, the importance of the State having been greatly increased by the efforts of the two illegitimate sons. In June, 1473, amid magnificent festivities, Ercole married Eleonora of Aragon, daughter of Ferdinand of Naples. Twenty-nine years—years of conflict—had passed when the second Duke of Ferrara married his son to Lucretia with similar pomp. By putting an end to the war with Venice and Pope Sixtus IV, in the year 1482, Ercole had succeeded in saving his State from the great danger which threatened it, although he had been forced to relinquish certain territory to the Venetians. This danger, however, might arise again, for Venice and the Pope continued to be Ferrara's bitterest enemies. Political considerations, therefore, compelled her to form an alliance with France, whose king already owned Milan and might permanently secure possession of Naples. For the same reason he had married his son to Lucretia on the best terms he was able to make. She, therefore, must have been conscious of her great importance to the State of Ferrara, and this it was which gave her a sense of security with regard to the noble house to which she now belonged.
The Duke presented the young couple Castle Vecchio for their residence, and there Lucretia established her court. This stronghold, which is still in existence, is one of the most imposing monuments of the Middle Ages. It overlooks all Ferrara, and may be seen for miles around. Its dark red color; its gloominess, which is partly due to its architectural severity; its four mighty towers—all combine to cause a feeling of fear, especially on moonlight nights, when the shadows of the towers fall on the water in the moat, which still surrounds the castle as in days of old. The figures of the great ones who once lived in the stronghold—Ugo and Parisina Malatesta, Borso, Lucretia Borgia and Alfonso, Renée of France, and Calvin, Ariosto, Alfonso II, the unfortunate Tasso and Eleonora—seem to rise before the beholder.
CASTLE VECCHIO AT FERRARA.
The Marchese Niccolò, owing to an uprising of the citizens began Castle Vecchio in the year 1385, and his successor completed it and decorated the interior. It is connected by covered passage-ways with the palace opposite the church. Before Ercole extended Ferrara on the north, the castle marked the boundary of the city. One of the towers, called the Tower of the Lions, protected the city gate. A branch of the Po, which at that time flowed near by, supplied the moat—over which there were several drawbridges—with water.
In Lucretia's time only the main features of the stronghold were the same as they are now; the cornices of the towers are of a later date, and the towers themselves were somewhat lower; the walls were embattled like those of the Gonzaga castle in Mantua. Cannon, cast under the direction of Alfonso, were placed at various points. There is an interior quadrangular court with arcades, and there Lucretia was shown the place where Niccolò II had caused his son Ugo and his stepmother, the beautiful Parisina, to be beheaded. This gruesome deed was a warning to Alexander's daughter to be true to her husband.
