History of Medicine Introduction The horse has been one of the most important animals throughout human history, and healing horses has had an important place in veterinary and medical literature. Theories about equine physiology and health often mirrored theories about humans, and the literature of both was inherently linked. Bloodletting, astrology, and ancient texts were used by both physicians and veterinarians to heal their patients, and many discoveries, including the circulation of the blood, developed in tandem. The Hippiatrica: Ancient Texts Medieval and Renaissance veterinary medicine looked to ancient veterinary texts for its inspiration, just as physicians for human healing did.
Eadweard Muybridge (1830–1904) wished to catalogue every aspect of human and animal locomotion with his camera. He photographed hundreds of subjects engaged in actions both mundane and arcane: nude figures walking and lifting children, athletes boxing and fencing, and animals hurdling, kicking, or slowly ambling along. He was the first photographer to visually dissect these activities, creating images that delighted and mystified the public in the late 19th century.
