‘Centaurs and other animals’ examines the final decade of Newton's life. Newton continued his relentless pursuit of religious truth: massive drafts on early church history survive, many related to his disputes with Leibniz. His extensive researches into chronology display a vast knowledge of classical and Old Testament literature. In attempting to radically redate recorded history, he used dramatic new astronomical evidence based on eclipses. He himself viewed his theological research as the defining aspect of his life, yet the astonishing courage, imagination, and originality that colour his achievements in optics, physics, and mathematics are more worthy of our admiration.
