Leonardo da Vinci’s notebook

These pages come from a notebook compiled by the artist and inventor, Leonardo da Vinci. They are written in Italian, in Leonardo’s mirror handwriting, reading from right to left. The shaded diagram in the centre right shows the Sun and Moon revolving round the Earth, accepting the theory that the Earth occupied the centre of the universe. Leonardo also believed that the Moon was covered with water, and that its surface would reflect light like a convex mirror. Shown here: f. 104r
