Leonardo da Vinci was educated in his father's house receiving the usual elementary education of reading, writing and arithmetic. In 1467 he became an apprentice learning painting, sculpture andacquiring technical and mechanical skills. He was accepted into the painters' guild in Florence in 1472 but he continued to work as an apprentice until 1477. From that time he worked for himself inFlorence as a painter. Already during this time he sketched pumps, military weapons and other machines.
Between 1482 and 1499 Leonardo was in the service of the Duke of Milan. He was described in a list ofthe Duke's staff as a painter and engineer of the duke. He was also considered as a hydraulic and mechanical engineer.
Leonardo studied Euclid and Pacioli's Suma and began his own geometry research,sometimes giving mechanical solutions. He gave several methods of squaring the circle, again using mechanical methods. He wrote a book, around this time, on the elementary theory of mechanics whichappeared in Milan around 1498.
Leonardo certainly realised the possibility of constructing a telescope and in Codex Atlanticus written in 1490 he talks of
... making glasses to see the Moon enlarged.In a later work, Codex Arundul written about 1513, he says that
... in order to observe the nature of the planets, open the roof and bring the image of a single planet onto the base of a concavemirror. The image of the planet reflected by the base will show the surface of the planet much magnified.
See [28] for more details of this quotation and more of Leonardo's ideas about the Universe. Heunderstood the fact that the Moon shone with reflected light from the Sun and he correctly explained the 'old Moon in the new Moon's arms' as the Moon's surface illuminated by light reflected fromthe Earth. He thought of the Moon as being similar to the Earth with seas and areas of solid ground.
In 1499 the French armies entered Milan and the Duke was defeated. Some months later Leonardo left...
