Ten illustrations from the National Library of Medicine History of Medicine collection were featured in a March 2009 Scientific American online story and slide presentation, “Anatomy Lessons through the Ages.” The story, using period text and images, provided a glimpse into the science of early medicine. Among the NLM illustrations were Johannes de Ketham’s 1490s depiction of a medieval dissection class, and a 1522 or 1523 illustration by the physician Jacopo Berengario da Carpi — probably the first printed work based on direct observation of the body. Andreas Vesalius’ 1543 volume On the Fabric of the Human Body, considered the first modern anatomical book, was also featured.
