Cosmografía

''Cosmografía'' by Amédée Guillemin is a scientific publication written in the late 19th century. The work examines the nature, structure, and movements of celestial bodies, including the Earth, Moon, and stars, providing insights into the foundational principles of cosmography. It serves both as an educational resource on astronomical phenomena and a study of how these celestial aspects interact with our understanding of the world. The opening of the book introduces cosmography as the study of various celestial bodies and their movements. It describes the diurnal movement of the heavens, noting the apparent motions of the sun, moon, and stars as observed from Earth. The text highlights the significance of perceiving the Earth as a celestial body in motion, detailing aspects such as the fixed positions of stars, the concept of planets, and the nature of day and night. The author emphasizes that our understanding of these movements leads to the recognition of the Earth's spherical nature and its place within the universe, setting a foundation for the topics that will be further explored throughout the publication.
