Who was Leonardo da Vinci?
Leonardo da Vinci was born in Tuscany, Italy, in 1452 - the illegitimate son of a farmer’s daughter.
He is known as one of the greatest artists who ever lived. His most famous works of art are The Last Supper and the Mona Lisa.
But there was much more to Leonardo than his paintings.
Despite little formal education, he kept extensive notebooks filled with his scientific theories, inventions, drawings and designs.
Leonardo wrote backwards, from right to left; his writing can be read normally if viewed in a mirror.
More than 4,000 pages have been found, but many are thought to have been lost.
