science and inventions




Leonardo Da Vinci is one of the greatest and most ingenious men that history has produced. His contributions in the areas of art, science, and humanity are still among the most important that a single man has put forth, definitely making his a life worth knowing. Da Vinci, born on April 15, 1452, is credited with being a master painter, sculptor, architect, musician, engineer, and scientist. He was born an illegitimate child to Catherina, a peasant girl. His father was Ser Piero da Vinci, a public notary for the city of Florence, Italy. For the first four years of his life he lived with his mother in the small village of Vinci, directly outside of the great center of the Renaissance, Florence. Catherina was a poor woman, with possible artistic talent, the genetic basis of Leonardo’s talents. Upon the realization of Leonardo’s potential, his father took the boy to live with him and his wife in Florence (Why did). This was the start of the boy’s education and his quest for knowledge. Leonardo was recognized by many to be a “Renaissance child” because of his many talents. As a boy, Leonardo was described as being handsome, strong, and agile. He had keen powers of observation, an imagination, and the ability to detach himself from the world around him. At an early age Leonardo became interested in subjects such as botany, geology, animals (specifically birds), the motion of water, and shadows (About Leonardo). At the age of 17, in about 1469, Leonardo was apprenticed as a garzone (studio boy) to Andrea del Verrocchio, the leading Florentine painter and sculptor of his day. In Verrocchio’s workshop Leonardo was introduced to many techniques, from the painting of altarpieces and panel pictures to the creation of large sculptural projects in marble and bronze. In 1472 he was accepted in the painter’s guild of Florence, and worked there for about six years. While there, Leonardo often painted portions of Verrocchio’s paintings for him, such as the background and the kneeling angel on the left in the Baptism of Christ (Encarta). Leonardo’s sections of the painting have soft shadings, with shadows concealing the edges. These areas are distinguished easily against the sharply defined figures and objects of Verrocchio, that reflect the style called Early Renaissance. Leonardo’s more graceful approach marked the beginning of the High Renaissance. However, this style did not become more popular in Italy for another 25 year (Gilbert 46). Leonardo actually started the popularization of this style. For this reason Leonardo could be called the “Father of the High Renaissance.” Leonardo’s leading skills emerged through his paintings and his techniques. Leonardo’s talents soon drew him away from the Guild and in 1472 Leonardo finished his first complete painting, Annunciation. In 1478 Leonardo reached the title of an Independent Master. His first large painting, The Adoration of the Magi (begun in 1481), which was left unfinished, was ordered in 1481 for the Monastery of San Donato a Scopeto, Florence. Other works ascribed to his youth are the Benois Madonna (1478), the portrait Ginevra de’ Benci (1474), and the unfinished Saint Jerome (1481). Leonardo expanded his skills to other branches of interest and in 1481 Leonardo wrote an astonishing letter to the Duke of Milan, Ludovico Sforza. In this letter he stated that he knew how to build portable bridges; that he knew the techniques of constructing bombardments and of making cannons; that he could build ships as well as armored vehicles, catapults, and other war machines; and that he could execute sculpture in marble, bronze, and clay. Thus, he entered the service of the Duke in 1482, working on Ludovico’s castle, organizing festivals, and he became recognized as an expert in military engineering and arms. Under the Duke, Leonardo served many positions. He served as principal engineer in the Duke’s numerous military enterprises and was active as an architect (Encarta). As a military engineer Leonardo designed artillery and planned the diversion of rivers. He also improved many inventions that were already in use such as the rope ladder. Leonardo also drew pictures of an armored tank hundreds of years ahead of its time. His concept failed because the tank was too heavy to be mobile and the hand cranks he designed were not strong enough to support such a vehicle. As a civil engineer, he designed revolving stages for pageants. As a sculptor he planned a huge monument of the Duke’s father mounted up on a leaping horse. The Horse, as it was known, was the culmination of 16 years of work. Leonardo was fascinated by horses and drew them constantly. In The Horse, Leonardo experimented with the horses' forelegs and measurements. The severe plagues in 1484 and 1485 drew his attention to town planning, and his drawings and plans for domed churches reflect his concern with architectural problems (Bookshelf). In addition he also assisted the Italian mathematician Luca Pacioli in the work Divina Proportione (1509). While in Milan Leonardo kept up his own work and studies with the possible help of apprentices and pupils, for whom he probably wrote the various texts later compiled as Treatise on Painting (1651). The most important painting of those created in the early Milan age was The Virgin of the Rocks. Leonardo worked on this piece for an extended period of time, seemingly unwilling to finish what he had begun (Encarta). It is his earliest major painting that survives in complete form. From 1495 to 1497 Leonardo labored on his masterpiece, The Last Supper, a mural in the refectory of the Monastery of Santa Maria delle Grazie, Milan. While painting The Last Supper, Leonardo rejected the fresco technique normally used for wall paintings. An artist that uses this fresco method must work quickly. Leonardo wanted to work slowly, revising his work, and use shadows-which would have been impossible in using fresco painting. He invented a new technique that involved coating the wall with a compound that he had created. This compound, which was supposed to protect the paint and hold it in place did not work, and soon after its completion the paint began to flake away. For this reason The Last Supper still exists, but in poor condition (Gilbert 46). Leonardo had at many times merged his inventive and creative capabilities to enhance life and improve his works. Although his experiments with plastering and painting failed, they showed his dissatisfaction with an accepted means and his creativity and courage to experiment with a new and untried idea. Experimentation with traditional techniques is evident in his drawings as well. During Leonardo’s 18 year stay in Milan he also produced other paintings and drawings, but most have been lost. He created stage designs for theater, architectural drawings, and models for the dome of Milan Cathedral. Leonardo also began to produce scie
