Listed in a Medici inventory dated 1553, the portrait was moved to various Florentine collections, meanwhile losing its identity.
Ironically named after the giant Morgante Maggiore in the 15th-century epic poem by Luigi Pulci, the dwarf is recorded to have arrived at the court of Cosimo I de' Medici (1519-74), Grand-Duke of Tuscany, around 1540.
According to Vasari, the dwarf was "clever, learned and very kind, the favorite of our Duke."
Indeed, historic accounts reveal that in 1555 the Grand Duke granted Braccio di Bartolo (this was the real name of the individual affected by achondroplasia dwarfism) a honor, calling him "our beloved dwarf."
"While Morgante entered the courts as a possession, he is mentioned in a document where Cosimo bequeathed him land and the right to marry. He was a faithful companion to Cosimo I de' Medici, and while he was asked to perform entertaining tasks, he also accompanied Cosimo on many diplomatic trips," Touba Ghadessi, assistant professor of art history at Wheaton College, Norton, Massachusetts, told Discovery News.
As the Duke's favourite jester, he was portrayed in several artworks. Sculptor Giambologna (1529-1608) mounted him on a dragon, while another sculptor, Valerio Cioli (1529-1599], immortalized him as the paunchy dwarf riding a tortoise in a sculpture at Boboli gardens.
According to Vasari, Bronzino's work was unique.
"He made a full-length portrait of the dwarf Morgante, nude, and in two ways - namely, on one side of the picture the front, and on the other the back, with the bizarre and monstrous members which that dwarf has; which picture, of its kind, is beautiful and marvellous," Vasari wrote.
The second half of the sixteenth century seems to have been a particularly populated time for dwarves at the Medici court.
"There is a series of engraving by Stradano showing the coronation of Cosimo and several dwarves are present," Ghadessi, who authored Identity and physical deformity in Italian court portraits 1550-1650, said.
Called "nani," the dwarfs entertained and amused, being the subject of fascination, laughter and ridicule.
Morgante's case was no exception. Records testify that he was often mortified, and even had to fight, naked, with a monkey.
"Although he had a privileged role, as a dwarf he suffered humiliation and physical violence by certain courtesans," art historian Sefy Hendler wrote in the exhibition's catalogue.
Made to respond to a heated debate over which art, sculpture or painting, was nobler, Bronzino's double faced portrait offered different viewpoints - just like a sculpture - as it depicted a popular court scene which amused the Grand Duke. According to historical accounts, Morgante was often employed as a nocturnal bird hunter (the technique used a trained owl to capture little birds).
Moreover, the portrait, showing both the beginning and the end of the bird hunting, demonstrated that painting can depict the passage of time, which sculpture cannot.
"The newly restored portrait provides a unique evidence for the history of this character at the Medici court and shows that Bronzino is not only a great mannerist painter, but one of the masters of Italian art," Natali said.
