Instead of a fake post, or some similar nonsense, let’s celebrate April Fool’s Day with a nice bit of “fool the eye” (trompe l’oeil) by Andrea Pozzo.
This is his false dome for the Jseuit Church in Vienna, a fresco painted on a gently curved surface on the ceiling. This is essentially a anamorphic projection, painted to look like the interior of a dome in deep, three-dimensional space when seen from a certain vantage point, in this case when standing in the entrance of the church.
You can see the image of the fresco viewed from the other direction (image above, bottom – from OpticalIllustions.net), where its painted distortions are obvious.
