The Universe Unveiled: Instruments and Images Through History

Book excerpt: The Universe Unveiled documents the human desire through history to explore and understand our world. Taking a unique approach, it focuses on the instruments, books, and maps people have created to decipher the Universe from the late fifteenth through to the nineteenth century. Throughout, the book is richly illustrated with over 270 full-color images, including those of rare and unusual artifacts from all over the world kept in the world-renowned collection at the Adler Planetarium and Astronomy Museum in Chicago.
