Sacrificial rituals were a common means to observe and learn about internal anatomy in ancient Greece. Aristotle investigated the body also by means of methodical dissections and vivisections of animals, ranging from mollusca and insects to pigs and bulls; and he often refers to pigs and dogs as sources for learning about human anatomy. Archaeological excavations have revealed tools used in such dissections, such as the hook in the foreground of the exhibit. Aristotle described his observations and understanding of internal anatomy in his zoological works, especially the treatise Inquiries of Animals, which, like other Ancient Greek writings, has reached us in form of manuscripts copied in the Middle Ages; at the top of the exhibit you can see the opening lines from one such manuscript.
