Book excerpt: Toxicology in Antiquity provides an authoritative and fascinating exploration into the use of toxins and poisons in antiquity. It brings together the two previously published shorter volumes on the topic, as well as adding considerable new information. Part of the History of Toxicology and Environmental Health series, it covers key accomplishments, scientists, and events in the broad field of toxicology, including environmental health and chemical safety. This first volume sets the tone for the series and starts at the very beginning, historically speaking, with a look at toxicology in ancient times. The book explains that before scientific research methods were developed, toxicology thrived as a very practical discipline. People living in ancient civilizations readily learned to distinguish safe substances from hazardous ones, how to avoid these hazardous substances, and how to use them to inflict harm on enemies. It also describes scholars who compiled compendia of toxic agents. New chapters in this edition focus chiefly on evidence for the use of toxic agents derived from religious texts. Provides the historical background for understanding modern toxicology Illustrates the ways previous civilizations learned to distinguish safe from hazardous substances, how to avoid the hazardous substances and how to use them against enemies Explores the way famous historical figures used toxins New chapters focus on evidence of the use of toxins derived from religious texts
