An epitome of astronomy, with the new discoveries including an account of the eídouraníon, or transparent orrery

"An Epitome of Astronomy, with the New Discoveries" by William Walker is a comprehensive scientific exploration of the cosmos, designed to unveil the mysteries of the universe to its readers. Serving as an educational guide, the book explores astronomical principles, focusing on the solar system, celestial bodies, and the laws that govern their movements. Walker employed a novel teaching method, utilizing a large, transparent orrery called the Eídouraníon to visually clarify celestial motions and phenomena, like planetary orbits and eclipses. The book carefully explains complex phenomena such as tides, the architecture of the solar system, and the essence of comets, all while employing jargon-free language accessible to the average reader. By doing this, Walker not only educates but also connects scientific explanations to philosophical ponderings on the nature of the universe and humanity's place in it.
