On March 5, 1495, 15-year-old Lisa married 29-year-old Francesco di Bartolomeo del Giocondo, an ambitious
cloth and
silk merchant, becoming his second wife. Her age at marriage was around the norm for Florentine women of the time, who often married men ten or more years their senior. Because her father had not participated in the custom of saving cash at a daughter's birth that compounded interest for
dowries, Lisa's dowry was land: her father's most valuable property in Chianti, the San Silvestro farm near her family's country home, which lies between Castellina and San Donato in Poggio, near two farms later owned by
Michelangelo. The farm was valued at 400
florins, and its contents at 170
florins. The modest dowry may be a sign that the Gherardini family was not wealthy at the time. Art historian
Frank Zöllner says the dowry's small size lends reason to think Francesco may have had true affection for Lisa. Neither poor nor among the most well-to-do in Florence, the couple lived a comfortable middle-class life. Historian Donald Sassoon says they were upwardly mobile and were among the city's
nouveaux riches. Lisa's marriage may have increased her social status because her husband's family may have been richer than her own. Francesco is thought to have benefited because Gherardini is an "old name". They lived in shared accommodation until March 5, 1503, when Francesco was able to buy a house next door to his family's old home in the Via della Stufa. Leonardo is thought to have begun painting Lisa's portrait the same year. Lisa lived in the "Casa grande" on Via della Stufa for nearly fifty years. Lisa and Francesco had six children: Piero, Piera, Camilla, Marietta, Andrea, and Giocondo between 1496 and 1502. Piera and Giocondo both died before they were toddlers. Lisa also raised two of her brother's children after their father's death. Lastly, she raised Bartolomeo, the son of Francesco and his first wife Camilla di Mariotto Rucellai, who died shortly after the birth. The second wife of Lisa's father, Caterina di Mariotto Rucellai, and Francesco's first wife were sisters, members of the Rucellai family. Camilla and Marietta became nuns. Camilla took the name Suor Beatrice and entered the convent of San Domenico di Cafaggio, where she was entrusted to the care of Lisa's sisters Suor Alessandra and Suor Camilla. Beatrice died at age 18, and was buried in the
Basilica di Santa Maria Novella. Adopting roles of a customer and supplier, Lisa developed a relationship with Sant'Orsola, a convent held in high regard in Florence. From the convent, Lisa is known to have purchased distillation of
snail water—a medicine listed in
formularies of following centuries. Kemp and Pallanti say on another occasion, the nuns purchased from Lisa of cheese made on her family's lands. She was able to place Marietta at Sant'Orsola in 1519. In 1521, Marietta took the name Suor Ludovica; she became a respected member of the convent in a position of some responsibility. Francesco was a social climber, and not known particularly for his rectitude. He had joined the family business, a respected source of fine textiles, where he had done well, but the promise of higher profits tempted him into other enterprises. He imported sugar, animal hides, wool, and soap. He became a money-lender and dealt in property. Believing that land was a safe investment, Francesco transformed himself into a wealthy landowner after thirty-five years of marriage to Lisa by 1530. As members of the Silk Guild, Francesco's family was eligible for the highest offices of Florence, and eighty of his relatives occupied such roles over a span of fifty years. Francesco was elected to the
Dodici Buonomini in 1499 and to the
Signoria in 1512, where he was confirmed as a
Priore in 1524. He may have had ties to
Medici family political or business interests; he was termed a "friend" rather than a "close friend". In 1512, when the government of Florence feared the return of the Medici from exile, Francesco was imprisoned and fined 1,000 florins. He was released in September when the Medici returned. == Death and outcome ==
