From Daedalus to the Wright Brothers to NASA flying a tiny helicopter on Mars, the concept of flight has fascinated humanity for millennia. This was no different for an 11th-century monk named Eilmer (AKA Elmer/Oliver. Oliver is due to a misreading). Eilmer of Malmesbury was briefly mentioned in William of Malmesbury’s Gesta regum Anglorum. Sadly this text is really the only surviving account we have about Eilmer. That being said, his works about astrology (now lost) were referenced as late as the 16th century.
What does an astrologer monk have to do with flight? Well, when Eilmer was a young monk he decided that he was going to try to fly. His plan included making wings and jumping off of Malmesbury Abbey’s tower. And it worked! Eilmer flew! Well, sort of. He flew for about six hundred feet before the wind became violent, the air current changed and he crash-landed. Fortunately for Eilmer, he survived the crash. Unfortunately for Eilmer, he broke both legs. His injuries were severe enough that according to William of Malmesbury he “was lame ever after.” Apparently, for the rest of his life, Eilmer lamented his experiment would have worked had he not forgotten to add a tail. (Some modern writers say that Eilmer’s abbot forbade him from doing a second experiment, but this is not in the primary source. Dom Aelred Watkin added this tidbit to his account in the 1950s. While not factually accurate, it certainly is funny to think about.)
There are a lot of myths/legends about people trying (and failing) to fly. However, it is extremely likely Eilmer’s experiment did in fact happen. For one, William is considered to be an extremely accurate medieval historian. It helps that William came from the same monastery as Eilmer and Eilmer died less than one hundred years before William finished his chronicle. William probably heard the story from monks who knew Eilmer as an old man.
When exactly did Eilmer attempt to fly? Well, we don’t have an exact date but Dr. Lynn White’s research does give us a general estimate of when it happened. See, Eilmer isn’t just famous for his flying. In fact, William seems to have added that as more of an after thought. William focuses more on how Eilmer had seen Halley’s comet twice in his life. This is very imporant for dating his life story. The second time he saw the comet was in 1066. Eilmer recognizes it as the comet he saw in his childhood. Because Halley’s comet appears every 75-76 years or so, the first time Eilmer saw it had to have been in 989. Assuming Eilmer was about five or six at the time (five to six being old enough to remember things) he would have been in his early 80s in 1066. William says Eilmer was in his early youth when he tried to fly, so he was probably less than 25 years old at the time of his experiment. This puts the date sometime from the years 1000 to 1010.
We don’t know for certain what Eilmer’s flying machine looked like, but we do have some clues thanks to William’s description, cultural context, and modern-day aviation. We do know Eilmer used wings he attached to his hands and feet. William uses the Latin term “pennae” when describing them so the contraption could not have been a parachute or a balloon of some sort. They were probably rigid, maybe hinged, and possibly meant to flap like a bird’s. (I will note that humans do not have the right muscle structure to fly by flapping their arms.) They would have to be pretty big to carry him. James of Wanborough theorizes that they were around 100 square feet, probably made of ash or willow (the wood most likely to be available to Eilmer at the time), and covered in a light cloth or parchment. Because Eilmer did in fact fly for a good distance before he crashed, he had to have been a small man. However, that is all scientific speculation.
Even though we no longer have his astrological works or really any other evidence of Eilmer’s existence besides William’s account, I want to stress how remembered he was throughout the Middle Ages. William was not the only historian to write about him. Some other medieval historians include (but are not limited to!) Helinand, Alberic, Vincent of Beavais, and Ralph Higden. Unfortunately, they all seemed to use William’s account as their source so they don’t have any new information about Eilmer. (In fact, Ralph Higden even misread Eilmer’s name as Oliver! Thanks to this, Eilmer was referred to as Oliver by other historians.) And it wasn’t just medieval people who were fascinated by Eilmer! From William’s chronicle to the modern day Eilmer is a figure who has fascinated generations.
Finally, as a little treat, I would like to share this YouTube video I found about Eilmer. It’s a short silent animation. I think you will enjoy it!
