Stone age monument defaced with 'alien' figures by unidentified vandals - 2020-01-14
In the second week of January, Cheryl Straffon of the Cornish Ancient Sites Protection Network (CASPN) announced that the megalithic structure Mulfra Quoit had been marred by graffiti, which should wash off, but will require professional restorers to work carefully, as this is a registered historic site.
CASPN looks in on sites about monthly, to clean up trash and so on, but has no way to determine whether this was done on winter solstice or New Year's or some such significant date. The painting depicts two vague humanoid figures, with halos around their heads which might put one in mind of medieval saints, except that the style of the figures and the color choice point rather to "Gray Aliens": this stereotyped depiction of extraterrestrials has become embedded in the culture, from Barney and Betty Hill's 1961 description of the "Zeta Reticulans" who they claimed abducted them, through the movie Close Encounters of the Third Kind, to the infamous Alien Autopsy hoax video.
Stone Age structures come in a few distinct types. In Europe and the Mideast, tall slender stones, alone or in clusters, and are called obelisks if carved square with pointy tips, or menhir "standing stones" if left rough. New Age literature sees these as drawing magnetic energy out of the Earth or down from the heavens.
