BOUILLIAU, Ismael Astronomia Philolaica   (Paris, 1645)

11 repeat

Ismael Bouilliau (1605-1694), also known as Ismael Bullialdus, was a French astronomer. He was ordained as a priest but worked as a librarian for much of his life. He was friendly with Huygens and Blaise Pascal and actively supported Galileo and Copernicus.

One of his most important works was the Astronomia Philolaica which proposed that the force of gravity follows an inverse-square law. Isaac Newton later proved his idea mathematically in the Principia and praised Bouilliau for the accurate tables and observations in this book.

Bouilliau was convinced that the success of the new science was dependent on a revival of the Pythagorean and Platonic scientific conceptions, and he named the book after Philolaus to show his belief that this man was the true founder of astronomy.
