Books are a place where fantasy intersects with reality. There is perhaps no better example than the most popular children's book series of this century, the Harry Potter books. They are filled with fantastical magic, and yet, with a closer look, we find much of it is based on yesterday's science, or "science" if you will. The New York Academy of Medicine delved deeper into the series and discovered much of what is known to be fiction today was based on real beliefs from centuries ago. Author J. K. Rowling didn't just have a fertile imagination, she also had a substantial knowledge of history. The New York Academy of Medicine is revealing that connection in a new digital collection: How to Pass Your O.W.L.s at Hogwarts: A Prep Course.

 

The Academy has divided its "prep course" into seven sections: Care of Mystical Creatures, Defense Against the Dark Arts, Divination, Herbology, History of Magic, Potions, and Transfiguration. Within these categories, you can find images and descriptions of items and processes either mentioned in the Potter books or similar to them. For example, you can peer at a basilisk, a serpent of sorts described in Rowling's books, but not for the first time. The Academy shows us a "real" one presented by Ulisse Aldrovandi in the late 16^th century. Where he came up with this creature is unclear, as nothing in nature looks much like it. In those days, such depictions were often created from tales by voyagers who traveled great distances exploring new worlds. Whether they made up their stories, heard tales from others, or just let their imaginations run wild is unclear, but these images were not created in the tradition of Dr. Seuss. Many were believed to be real.

 

Perhaps the most fascinating object displayed is the bezoar. That is Persian for "antidote." It was used to neutralize poisons. It makes its appearance in the Harry Potter books as an ingredient in potions, but the thing was actually used as an antidote many centuries ago. Once upon a time it was believed to cure any kind of poisoning. Essentially, a bezoar a hairball, a giant hairball your cat could not imagine in its worst nightmares. This thing is more baseball size and comes from the stomach of a cow. Why it was thought to be a cure-all is mystifying, since it wouldn't have taken much testing to realize it was a failure, but the scientific method was not in use in those days. People just reached conclusions and those conclusions, if from "experts," were accepted. This sounds incomprehensible, but then again, you can find a myriad of herbal and other supplements and medicines at drug and health food stores with no more scientific testing than was conducted on bezoars in the 16^th century. That doesn't stop people from shelling out their money. Perhaps we have not come such a long way after all.
