Context: Leonardo di ser Piero da Vinci (] ; 15 April 14522 May 1519), more commonly Leonardo da Vinci or simply Leonardo, was an Italian Renaissance polymath whose areas of interest included invention, painting, sculpting, architecture, science, music, mathematics, engineering, literature, anatomy, geology, astronomy, botany, writing, history, and cartography.  He has been variously called the father of palaeontology, ichnology, and architecture, and is widely considered one of the greatest painters of all time.  Sometimes credited with the inventions of the parachute, helicopter and tank, he epitomised the Renaissance humanist ideal. The viola organista is a musical instrument designed by Leonardo da Vinci.  It uses a friction belt to vibrate individual strings (similar to how a violin produces sounds), with the strings selected by pressing keys on a keyboard (similar to an organ).  Leonardo's design has intrigued instrument makers for more than 400 years.  But though similar instruments have been built, no extant instrument constructed directly from Leonardo's incomplete designs is known. The Lucan portrait of Leonardo da Vinci is a late 15th or early 16th century portrait of a man that was recently discovered in a cupboard of a private house in Italy.  It strongly resembles a portrait of Leonardo da Vinci held by the Uffizi Gallery and regarded by experts as a forgery.  The painting was previously thought by its owners to represent Galileo but on its discovery in 2008 a claim was made that it is a self-portrait by Leonardo da Vinci.  Alessandro Vezzosi, director of the Museo Ideale Leonardo da Vinci at Vinci said in 2011 that he had excluded the possibility that it was a self-portrait, but that the painting "remains intriguing because it adds a new element to the Leonardo puzzle". The Leonardeschi is the large group of artists who worked in the studio of or under the influence of Leonardo da Vinci.  In 1472 da Vinci joined the Guild of St Luke and at the end of 1477 he left the studio of Andrea del Verrocchio as an independent artist.  In 1482 Leonardo came to Milan where he stayed with Giovanni Ambrogio de Predis, Evangelista de Predis and their four brothers, who all were artists of different kinds.  Both Predis brothers are known for having collaborated with Leonardo da Vinci in the painting of the "Virgin of the Rocks" for the altarpiece in the chapel of the Confraternity of the Immaculate Conception at the Church of San Francesco Grande, Milan.  In 1490 Leonardo earned recognition and a breakthrough at the court of Ludovico Sforza and because of the scale of works commissioned he was permitted to have assistants and pupils in his own studio. The Leonardo da Vinci Award was established in 1975 by the Rotary Club of Florence as an annual international prize named after Leonardo da Vinci, to be presented to young people involved in the study of the sciences, technology, literature and the arts.  Among the disciplines recognised and rewarded so far have been painting, sculpture, music, geology, architecture, medicine and nuclear physics.  The 21st Leonardo da Vinci Prize was recently presented to the brilliant young pianist Johan Schmidt.  The prize giving event has been hosted by other European Rotary Clubs in cities such as Tours, Vienna, Athens, Madrid, Würzburg, Brussels and Amsterdam.  This event was last held in London in 1987, when the prize was awarded to the internationally recognised percussionist Evelyn Glennie.  In 1996 1/2 the Rotary Club of London will again be responsible for hosting the prize-giving ceremony. Leonardo da Vinci (1452–1519) was an Italian polymath, regarded as the epitome of the "Renaissance Man", displaying skills in numerous diverse areas of study.  Whilst most famous for his paintings such as the "Mona Lisa" and the "Last Supper", Leonardo is also renowned in the fields of civil engineering, chemistry, geology, geometry, hydrodynamics, mathematics, mechanical engineering, optics, physics, pyrotechnics, and zoology. The Baptism of Christ is a painting finished around 1475 in the studio of the Italian Renaissance painter Andrea del Verrocchio and generally ascribed to him and his pupil Leonardo da Vinci.  Some art historians discern the hands of other members of Verrocchio's workshop in the painting as well.  The picture depicts the Baptism of Jesus by John the Baptist as recorded in the Biblical Gospels of Matthew, Mark and Luke.  The angel to the left is recorded as having been painted by the youthful Leonardo, a fact which has excited so much special comment and mythology, that the importance and value of the picture as a whole and within the œuvre of Verrocchio is often overlooked.  Modern critics also attribute much of the landscape in the background and the figure of Christ to Leonardo da Vinci as well.  The painting is housed in the Uffizi Gallery in Florence. La Vita di Leonardo Da Vinci — in English, The Life of Leonardo da Vinci — is a 1971 Italian television miniseries dramatizing the life of the Italian Renaissance genius Leonardo da Vinci (1452–1519). Da Vinci usually refers to Leonardo da Vinci (1452–1519), Italian Renaissance polymath.  It may also refer to: The wheelharp is a musical instrument with bowed strings controlled by a keyboard and foot-controlled motor, similar to Leonardo da Vinci's Viola organista, a keyboard-operated string instrument for continuously sounding strings by rubbing the strings with spinning wheels, powered by a treadle controlled by one foot of the musician.  Created by Jon Jones and Mitchell Manger, the wheelharp debuted at the 2013 NAMM Show in Anaheim, California.
