|These Roman columns are not architecturally stable|
This Roman column optical illusion is my favorite-looking illusion of this particular type of two-dimensional impossible object. It’s based on the impossible pronged trident optical illusion, also known as a blivet. As far as I can tell, it originated in the 1960s. It was published on a cover of MAD Magazine in March 1965 and called the "MAD poiuyt." It was also published in various science and science-fiction magazines a year earlier (in May and June 1964). And, in the same year, D.H. Schuster published the figure, later called the "Schuster Fork," in an article in the American Journal of Psychology. Similar deceptive drawing principles are used in M. C. Escher’s work.
