like the Ferrarese ambassador who commented: "she was so beautiful and radiant that she seemed like the sun". The operetta was written very much with this praise for Isabella in mind. Il Paradiso was the representation of the seven planets orbiting round. A man portrayed each of the planets and all would speak praise of Isabella. Therefore, the operetta depicted Isabella as being at the centre of the universe. In addition to the acknowledgment of her physical appearance, Isabella was also noted for having an energetic personality; Gian Galeazzo, on the other hand, was quite a contrast to his wife; he was pale, studious and melancholy. The differences of personality would certainly affect the marriage as well as in politics during the 1490s. First years in Milan Soon after the wedding, the spouses moved against their will to Pavia, where Gian Galeazzo's uncle and Regent Ludovico Sforza prepared their seat. Isabella's relationship with her uncle was not going well. The Duchess, on the other hand, had a great liking for Ludovico's lover, Cecilia Gallerani. Isabella's marriage was also unsuccessful at first. After the wedding, Gian Galeazzo did not intend to consummate the union. In April 1490, reports of Isabella's continuing virginity even reached the Hungarian court to her aunt, Queen consort Beatrice of Aragon. Soon, however, Gian Galeazzo, after almost thirteen months, decided to finally began to had sexual relations with his wife, and Isabella became pregnant in May 1490. On 30 January 1491, during the wedding celebrations of Ludovico Sforza and Beatrice d'Este, Isabella gave birth to a son, named Francesco Maria in honor of both hers and her husband's grandfather Francesco I Sforza. This worried Ludovico, since the birth of the heir could made Gian Galeazzo and Isabella as potential figureheads for opposition to his position as Regent, which he was unwilling to reliquish. In order to weaken any coup attempts made by Isabella and her husband, Ludovico had her Neapolitan retinue returned home and restricted the young Duchess from appointing and rewarding followers. Despite the initial good understanding between Isabella and Beatrice, soon arosed serious disputes over precedence: despite being the Duchess consort and thus the highest ranking woman at the Milanese court, Isabella was displaced by Ludovico's wife: Leonardo da Vinci was active in creating pageants and decorations in honour of Beatrice, and she was even given a political role, acting as ducal ambassador to Venice
