Isabella di Aragona (October 2, 1470 ? February 11, 1524) was born a princess of Naples, granddaughter of King Ferdinand I of Naples and daughter of King Alphonse II of Naples by his wife, Ippolita Maria Sforza. From 1489 to 1494 she was the Duchess Consort of Milan, and from 1499 to 1524 the Duchess of Bari and Princess of Rossano. After her brother Ferdinand II's death, she was the heir of the Brienne claim to the title King of Jerusalem.
She married her first cousin Gian Galeazzo II Maria Sforza, who at the time was the Duke of Milan. However, his uncle Ludovico Sforza was the de facto ruler.
With Gian Galeazzo II Maria Sforza she had one son and three daughters:
Francesco, who was taken to France by the French King Louis XII. in 1499,
Bona, who married King Sigismund I of Poland,
Bianca Maria (1495-1496).
Isabella outlived Francesco, who was killed in 1512 by falling from his horse. Of her three children, only Bona survived her.
In the 1970s Robert Payne was the first to suggest that Isabella was the subject of the Mona Lisa, the portrait by Leonardo da Vinci whose subject was traditionally thought to be Lisa Gherardini or Lisa del Giocondo. In 2003 historian Maike Vogt-Lüerssen concurred with Payne and argued that the subject was a member of the House of Sforza because of the pattern on the subject's dark green dress. The 2005 discovery of a note by Agostino Vespucci is commonly used to diminish this theory. However, since Vespucci does not provide any description of the painting, it could refer to any of Leonardo's female portrait paintings of that time.
