Oh, dear. I've often said that "you can find heraldry everywhere," but "everywhere" really doesn't, to my mind, involve extraterrestrials or . Not everyone, apparently, would limit the search in that way.
In an article in The Sun on June 22, 2011 (http://www.thesun.co.uk/sol/homepage/news/3652403/Coat-of-arms-crops-up-in-field.html), a quasi-heraldic crop circle that some say resembles an ancient coat of arms appeared overnight in a field. The crop circle was photographed at West Woods, near Marlborough, Wiltshire, by crop circle expert Lucy Pringle. I am not at all certain where Ms. Pringle's expertise comes from, or even which side of the "crop circles are made by extraterrestrials" or "crop circles are made by human hoaxers" she falls. (There are some nice articles about crop circles over at the Skeptical Inquirer, including this one: http://www.csicop.org/si/show/circular_reasoning_the_mystery_of_crop_circles_and_their_orbs_of_light/)
Ms. Pringle goes on to state that "Similar to the Cross Toulouse, it is assumed that the bearer of this cross was a crusader from the area of Toulouse." (It is "assumed," but on what basis? I could assume - I don't, but I could - that it was made by extraterrestrial Knights Templar from a planet orbiting the star Betelgeuse, but I have absolutely no evidence with which to support that assumption. So what then makes her assumption any more likely than the one I posit as an example?)
And just how similar is the cross in this field to a cross of Toulouse, anyway? The image below is a cross of Toulouse. Compare it to the crop circle above, and decide for yourself how "similar," or not, it the two are.
