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.
