. The generaly known as Leonardo's world map it's a map drawn in the "octant projection" in approximately 1514, which has been related with the first uses of the name America. The possibility that the map really small fragments of a rough map of the papers collected from Leonardo da Vinci preserved in London, had been drawn by Leonardo himself.〔Muntz, p. 317.〕 According to Mayor, who published the map in 1865 and defended its authenticity, the date indicated would be doubtful also because Florida is drawn as an island with the name of TERRA FLORIDA, while in maps Cosa 1500 and the Cantino of 1502 appears as a peninsula, where Leonardo deduced that should be before 1514. In fact Ferdinand Columbus mentions the Island before 1492 "and upon returning they found the island of flowers .." 〔 The map shows all the information that Amerigo Vespucci brought from his travels, reported in 1503 and 1505.〔 == Description == The area of the world is divided into eight spherical equilateral triangles, each section bounded by the Equator and two meridians with 90% difference. This was the first map of this type.〔 Some critics believe that the map was not really work the same Leonardo, since the precision and expertise in the drawing does not reflect the usual high standards of da Vinci. It was probably done by a trusted employee or copyist at Leonardo's workshop .〔 Leonardo's authorship would be demonstrated by Christoher Tyler in his paper entitled "Leonardo da Vinci’s World Map". It was documented by R.H. Major in his work'' Memoir on a mappemonde by Leonardo da Vinci, the earliest map Being Known hitherto container containing the name of America '' Grothe, The name of "Florida" (Terra Florida), correctly placed opposite Cuba although in form of "an island", was probably used for the first time on Leonardo's globe, one year after Ponce de Leon's expedition to Florida. The eight triangles are oriented in a similar way as per two four leaf clovers side by side, being the earth poles in the center of each clove. One of the sides of the eight triangles, (the one opposite to the center of the pseudo clover), its one fourth of the equator, the remaining two (those tha converge to the center of the pseudo clover), are of the two meridien that with the equator dissect the globe into eight octants. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Leonardo's world map」の詳細全文を読む スポンサード リンク
