Galileo's theories of observations from 'Il Saggiatore' (1623, 'The Assayer'). This work by Italian astronomer Galileo Galilei (1564-1642), was about comets and contained treatises on natural philosophy and mathematics. The illustration on this page shows the optics of a human eye observing a candle flame, with the accompanying text talking about observations made of stars using a telescope. | |
