The Science of Animal Locomotion (Zoopraxography)
 An Electro-Photographic Investigation of Consecutive Phases of Animal Movements

by Eadweard Muybridge

"The Science of Animal Locomotion (Zoopraxography)" by Eadweard Muybridge is a scientific publication produced in the late 19th century. This work outlines the author's extensive investigation into animal movements through innovative photographic techniques, showcasing the various phases of locomotion in animals. The book is notable for its systematic use of photography to analyze and depict the mechanics of movement, marking an important development in the study of motion. The content of the book primarily focuses on the results of Muybridge's groundbreaking experiments that began in 1872, where he aimed to capture the dynamic actions of animals, particularly horses, in motion. Using a specially designed electro-photographic apparatus, Muybridge took thousands of sequential images that illustrate the distinct phases of movements like walking, trotting, galloping, and more. It features over 20,000 figures across 781 plates, demonstrating the movements of a wide array of subjects including humans and various animals engaged in both everyday activities and athletic performances. This richly illustrated work serves not only as a scientific reference but also greatly influenced artists and animators in their understanding of motion dynamics.
