“Iron rusts from disuse, stagnant water loses its purity and in cold weather becomes frozen; even so does inaction sap the vigor of the mind.”—Leonardo da VinciWho Was Leonardo da Vinci?Leonardo da Vinci (April 15, 1452 to May 2, 1519) was a painter, sculptor, architect, inventor, military engineer and draftsman — the epitome of a “Renaissance man.” With a curious mind and keen intellect, da Vinci studied the laws of science and nature, which greatly informed his work. His ideas and body of work have influenced countless artists and made da Vinci a leading light of the Italian Renaissance.!Leonardo da Vinci’s Paintings and ArtworkAlthough da Vinci is known for his artistic abilities, fewer than two-dozen paintings attributed to him exist. One reason is that his interests were so varied that he wasn’t a prolific painter. Leonardo da Vinci’s most famous works include the “Vitruvian Man,” “The Last Supper” and the “Mona Lisa”.‘Vitruvian Man’Art and science intersected perfectly in da Vinci’s sketch of “Vitruvian Man,” drawn in 1490, which depicted a male figure in two superimposed positions with his arms and legs apart inside both a square and a circle. The sketch represents Leonardo’s study of proportion as well as his desire to relate man to nature.A sketch of Leonardo da Vinci.'The Last Supper'!Around 1495, Ludovico Sforza, then the Duke of Milan, commissioned da Vinci to paint “The Last Supper” on the back wall of the dining hall inside the monastery of Milan’s Santa Maria delle Grazie. The masterpiece, which took approximately three years to complete, captures the drama of the moment when Jesus informs the Twelve Apostles gathered for Passover dinner that one of them would soon betray him. The range of facial expressions and the body language of the figures around the table bring the masterful composition to life.!The decision by da Vinci to paint with tempera and oil on dried plaster instead of painting a fresco on fresh plaster led to the quick deterioration and flaking of “The Last Supper.” Although an improper restoration caused further damage to the mural, it has now been stabilized using modern conservation techniques.!!‘Mona Lisa’In 1503, da Vinci started working on what would become his most well known painting — and arguably the most famous painting in the world —the “Mona Lisa.” The privately commissioned work is characterized by the enigmatic smile of the woman in the half-portrait, which derives from da Vinci’s sfumato technique.Adding to the allure of the “Mona Lisa” is the mystery surrounding the identity of the subject. Princess Isabella of Naples, an unnamed courtesan and da Vinci’s own mother have all been put forth as potential sitters for the masterpiece. It has even been speculated that the subject wasn’t a female at all but da Vinci’s longtime apprentice Salai dressed in women’s clothing. Based on accounts from an early biographer, however, the "Mona Lisa" is a picture of Lisa del Giocondo, the wife of a wealthy Florentine silk merchant. The painting’s original Italian name — “La Gioconda” — supports the theory, but it’s far from certain. Some art historians believe the merchant commissioned the portrait to celebrate the pending birth of the couple’s next child, which means the subject could have been pregnant at the time of the painting.If the Giocondo family did indeed commission the painting, they never received it. For da Vinci, the "Mona Lisa" was forever a work in progress, as it was his attempt at perfection, and he never parted with the painting. Today, the "Mona Lisa" hangs in the Louvre Museum in Paris, France, secured behind bulletproof glass and regarded as a priceless national treasure seen by millions of visitors each year.‘Battle of Anghiari’In 1503, da Vinci also started work on the “Battle of Anghiari,” a mural commissioned for the council hall in the Palazzo Vecchio that was to be twice as large as “The Last Supper.” He abandoned the project after two years when the mural began to deteriorate before he had a chance to finish it.SculpturesLudovico Sforza also tasked da Vinci with sculpting a 16-foot-tall bronze equestrian statue of his father and founder of the family dynasty, Francesco Sforza. With the help of apprentices and students in his workshop, da Vinci worked on the project on and off for more than a dozen years. Leonardo sculpted a life-size clay model of the statue, but the project was put on hold when war with France required bronze to be used for casting cannons, not sculptures. After French forces overran Milan in 1499 — and shot the clay model to pieces — da Vinci fled the city along with the duke and the Sforza family. !Ironically, Gian Giacomo Trivulzio, who led the French forces that conquered Ludovico in 1499, followed in his foe’s footsteps and commissioned da Vinci to sculpt a grand equestrian statue, one that could be mounted on his tomb. After years of work and numerous sketches by da Vinci, Trivulzio decided to scale back the size of the statue, which was ultimately never finished.Painting TechniquesLeonardo da Vinci is well known for his pioneering use of two painting techniques:Chiaroscuro: a stark contrast between darkness and light that gave a three-dimensionality to da Vinci’s figures.Sfumato: a technique in which subtle gradations, rather than strict borders, infuse paintings with a softer, smoky aura.His painting “Virgin of the Rocks,” begun in 1483, is a classic example of both of these techniques.Inventions: The Flying MachineA man ahead of his time, da Vinci appeared to prophesy the future with his sketches of machines resembling a bicycle and a helicopter. Perhaps his most well-known “invention” is a “flying machine,” which is based on the physiology of a bat.When and Where Was da Vinci Born?Leonardo da Vinci was born on April 15, 1452, in a farmhouse nestled amid the undulating hills of Tuscany outside the village of Anchiano, in present-day Italy.!Family, Education and Early LifeBorn out of wedlock to respected Florentine notary Ser Piero and a young peasant woman named Caterina, Leonardo da Vinci was raised by his father and his stepmother. At the age of five, he moved to his father’s family estate in nearby Vinci, the Tuscan town from which the surname associated with Leonardo derives, and lived with his uncle and grandparents.Young Leonardo received little formal education
