Fioretta Gorini (1453/60 – possibly 1478)[1][2][3] was the mistress of Giuliano de' Medici and the probable mother of Giulio de' Medici, the future Pope Clement VII. Gorini was the daughter of a professor, Antonio Gorini.[4] Her actual name was Antonia or Antonietta, while Fioretta was a nickname given to her.[5]
On 26 May 1478, a month after the assassination of Giuliano in the Pazzi conspiracy, Fioretta gave birth to his illegitimate son, Giulio.[6] Not much of Gorini's life after her son's birth is known, and some records have her dying that same year.[2] Giulio spent the first seven years of life with his godfather, architect Antonio da Sangallo the Elder.[7]
