Mona Lisa Coming Back from the Grave?

Lisa Gherardini is coming closer to emerging from the grave. The remains of the woman believed to have inspired Leonardo da Vinci's Mona Lisa likely are about to be exhumed by researchers.

The announcement, at a news conference in Florence, follows the discovery of another skeleton, the fourth since the bone hunt began last year -- beneath an altar in the church of the now-derelict Convent of St. Orsola.

"The skeleton doesn't belong to the Mona Lisa, but it’s hinting to her burial. Indeed, she might be just underneath," Silvano Vinceti, president of a private organization known as the National Committee for the Promotion of Historic and Cultural Heritage, told a news conference on Wednesday.

Vinceti’s ambitious project aims to possibly reconstruct Lisa's face in order to see if her features match that of the iconic painting hanging at the Louvre Museum in Paris.

Indeed, most scholars believe that the Mona Lisa, known as La Gioconda in Italian or La Joconde in French, is the portrait of Lisa Gherardini, a member of a minor noble family of rural origins who married the wealthy merchant Francesco del Giocondo.

Known for controversial claims, like that letters and numbers are hidden inside the Mona Lisa painting, Vinceti has based his search in the convent on documents found by historian Giuseppe Pallanti some years ago.

The historian, who is not involved in the project, traced back Lisa's life from her birth on June 15, 1479, to her death at the age of 63.

Pallanti found several important documents, such as Francesco del Giocondo's will. There, the merchant asked his younger daughter, Marietta, to take care of his "beloved wife," Lisa.

At that time, Marietta, one of Lisa and Francesco's five children, had become a nun, so she brought her mother to the nearby convent of Sant'Orsola.

Lisa remained there until her death on July 15, 1542, according to a document known as a "Book of the Dead," found by Pallanti in a church archive.

The record noted that the whole parish turned out for her funeral, showing that Lisa was rather famous in Florentine society.

According to Vinceti, ancient documents also appear to support the latest skeletal discovery.

"The ledgers kept by the nuns tell us that the skeleton belongs to Maria Del Riccio, a wealthy woman who died in 1609," Vinceti said.

He added that only Maria Del Riccio and Lisa Gherardini, who were not nuns, were given special burials in the convent.
