June 29, 1539 marked Eleanor and Cosimo's grandiose entrance from the Porta al Prato to the Church of San Lorenzo for their wedding in a grand, lavish celebration. Painter Agnolo Bronzino provided festive decor, the first instance for artistic renewal in Florence after the disastrous Siege in 1529-1530. This showed the new Duke's policy of "creating an organic relationship between artists and the principality." The couple had a peaceful domestic life: surprisingly for the era, her husband was faithful throughout their long marriage. The ducal couple served as an example of a traditional couple, which served to strengthen Cosimo's various reforms and separate their association with the former Duke, who was assassinated by another member of the Medici family without leaving legitimate heirs and consolidating the dynasty's strength in Tuscany after years of politically damaging speculation about his excesses and sexual irregularities. He was reputed to have been the son of a black serving woman and Cardinal Giulio de' Medici, later Pope Clement VII, illegitimate son of Giuliano de' Medici, who was assassinated in the Pazzi Conspiracy against the reigning family.
