Also known as Crop Circles in English, it is called cerealogy those drawings or figures in the crops, crops, pastures, crop circles, which appear surprisingly in crops either wheat or corn, they have also been detected in sandy soils, they are usually created at night and the owners of the land notice these figures in the morning.
The concept of these circles or figures in crops was first coined by Doug Bower and Dave Chorley in the late 60s, in 1991 they confessed to having been the authors of approximately 200 circles, inspired by a formation that appeared in Queensland, a farmer was the one who reported having found the circles and assured that he saw a UFO flying over the sector. The first reports of this type circulated during 1678 news or publication that had the name The Mowing-Devil in Spanish El diablo reaper, where it showed a demon cutting a large circle made in a crop in the form of circles, considered as a crop circle, however the researcher Jim Schnabel did not consider it as a historical event since the published text did not describe the folded plains but cut.
For the year 1686 Robert Plot (Naturalist) reported circular shapes in mushrooms, which later later were considered to be caused by strong air currents which created their shapes. In 1880 John Rand Capron described various circular shapes that appeared in a field after a great storm, and it was considered but not confirmed that air currents were the protagonists of these figures or drawings.
