Horses revolutionized the way we hunted, traded, traveled, farmed, fought, worshipped, and interacted. They reshaped the human genome and the world's linguistic map. They determined international borders, molded cultures, fueled economies, and built global superpowers. And they were vectors of lethal disease and contributed to lifesaving medical innovations. Timothy Winegard's 'The Horse' is a riveting narrative of this noble animal's unrivaled and enduring reign across human history.
