Okay, is WASN'T Jonathan Swift in Gulliver's Travels who wrote of the Monopods. My daughter Christina corrected me. The most notable reference to the legend was from C.S. Lewis in Voyage of the Dawn Treader.
But the picture above, "borrowed" from Wikipedia, is captioned, "A monopod. From the Nuremberg Chronicle (1493)." So the legend has been around a long time. In fact I also found reference to the writings of Pliney in ancient Greece that are supposed to mention monopods.
There. I was wrong. But I've set the record straight, I think.
For those of you who thought I was never wrong, that was just a test. (Ha!)
