Leonardo was educated at Bugia, and afterwards toured the Mediterranean.
He received the first elements of his artistic education from Cosimo Roselli; and after leaving him, devoted himself to the study of the great works of Leonardo da Vinci.
Leonardo da Vinci's rough map of the world in 8 segments (c. 1513) seems likewise to have been intended for a globe.
Leonardo cannot be regarded as the inventor of that very great variety of truths for which he mentions no earlier source.
LEONARDO OF PISA (LEONARDUS PISANUS Or Fibonacci), Italian mathematician of the 13th century.
