Francesco Maurolico (Maurolycus), 1494–1575, a mathematician of Messina, and the great astronomer of his day, wrote De Subtilitate, about 1520, in which Pliny, Albertus Magnus, and Leonardo da Vinci are mentioned. The material included a mathematical, rather than experimental, discussion of light, mirrors and light theatres. This last subject shows that the use of light and shadow for theatrical purposes was being rapidly advanced. In 1521, Maurolico was said to have finished Theoremata de lumine et umbra ad perspectivam et radiorum incidentiam facientia, which was published in 1611 at Naples and in 1613 at Leyden. This book explained how a compound microscope could be fashioned. Men were now learning how to use lenses and how to make better ones so necessary for satisfactory projection of images.
