"Medicine is itself a type of technology, involving therapeutic tools and substances, and so one way to write the history of medicine is as the application of different technologies to the human body. In Tools and the Organism, Colin Webster argues that, over the course of antiquity, notions shifted about what type of object a body is, what substances constitute its essential nature, and how its parts interact. By following these changes and taking the question of technology into the heart of Greek and Roman medicine, Webster reveals how the body was first conceptualized as an "organism"-a functional object whose inner parts were tools [organa] that each completed certain vital tasks. Webster's approach provides both an overarching survey of the ways that technologies impacted notions of corporeality and corporeal behaviors and, at the same time, stays attentive to the specific material details of ancient tools and how they informed assumptions about somatic structures, substances, and inner processes. For example, by turning to developments in water-delivery technologies and pneumatic tools, we see how these changing material realities altered theories of the vascular system and respiration across Classical antiquity. Tools and the Organism makes the compelling case for why telling the history of ancient Greco-Roman medical theories, from the Hippocratics to Galen, should pay close attention to the question of technology.
