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.
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).
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.
The Leonardo da Vinci Society for the Study of Thinking and the Da Vinci Medallion were created to award scholarship in the realm of human thinking.
 The name was chosen to honor Leonardo da Vinci, the archetypal Renaissance man.
A four funnel liner, four funnelled liner or four stacker is an ocean liner with four funnels.
 The SS "Great Eastern", launched on 31 January 1858 (a full 40 years ahead of any comparable ships), was the only ocean liner to sport five funnels.
 As one funnel was later removed, the "Great Eastern", by default, became the first ocean liner to have four funnels.
 However, after the Great Eastern became a four funnel ship she never carried passengers so really should not be considered the first four funnel liner.
 The SS "Kaiser Wilhelm der Grosse", launched on 4 May 1897, was properly the first ocean liner to have four funnels and was one of the first of the golden era of ocean liners that became prominent in the early- to mid-20th century.
 The most famous four funnel liners are the RMS "Titanic", which sank after striking an iceberg on her maiden voyage on 14 April 1912, and the RMS "Lusitania", which was torpedoed on 7 May 1915 during the First World War.
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".
Leonardo da Vinci and A Memory of His Childhood (German: "Eine Kindheitserinnerung des Leonardo da Vinci" ) is a 1910 essay by Sigmund Freud about Leonardo da Vinci's childhood.
 It consists of a psychoanalytic study of Leonardo's life based on his paintings.
Istituto Leonardo da Vinci or Istituto di Istruzione Superiore Leonardo da Vinci (IIS Leonardo da Vinci) may refer to:
SS "Andrea Doria", ] , was an ocean liner for the Italian Line (Società di navigazione Italia) home ported in Genoa, Italy, most famous for her sinking in 1956, when 46 people were killed.
SS "Leonardo da Vinci" was an ocean liner built in 1960 by Ansaldo Shipyards, Italy for the Italian Line as a replacement for their SS "Andrea Doria" that had been lost in 1956.
 She was initially used in transatlantic service alongside SS "Cristoforo Colombo", and primarily for cruising after the delivery of the new SS "Michelangelo" and SS "Raffaello" in 1965.
 In 1976 the "Leonardo da Vinci" became the last Italian Line passenger liner to be used in service across the North Atlantic.
 Between 1977 and 1978 she was used as a cruise ship by Italia Crociere, but was laid up from 1978 onwards until 1982 when she was scrapped.
