"Descriptive Zoopraxography; or, the science of animal locomotion made popular" by Eadweard Muybridge is a scientific publication written during the late 19th century. This book serves as a popular treatise on Muybridge's groundbreaking investigations into animal locomotion, utilizing photographic techniques to examine and illustrate the movement of various animals. The book presents a synthesis of Muybridge's earlier work, particularly focusing on the detailed analysis of movements, especially of quadrupeds like horses, and how these movements correlate to artistic representations throughout history. With a systematic approach, Muybridge details the various gaits of animals—such as walking, trotting, galloping, and jumping—by describing their mechanics and providing photographic evidence from his extensive research. The Zoöpraxiscope, a device invented by Muybridge to project images of motion, plays a pivotal role in this work, illustrating how the principles of locomotion can aid both the scientific and artistic communities in understanding animal movement and enhancing accuracy in artistic representations.
