Leonardo da Vinci's rough map of the world in 8 segments (c. 1513) seems likewise to have been intended for a globe.
Received an impulse, largely, it is true, from the Arabs of Spain, but also from the East; Leonardo Fibonacci, the first Christian algebraist, had travelled in Syria and Egypt.
Leonardo da Vinci, the famous artist, while in the service of Cesare Borgia as military engineer, made surveys of several districts in central Italy.
His father was called Bonaccio, most probably a nickname with the ironical meaning of "a good, stupid fellow," while to Leonardo himself another nickname, Bigollone (dunce, blockhead), seems to have been given.
Leonardo was educated at Bugia, and afterwards toured the Mediterranean.
