Here's a case of pareidolia from 1927. That was the year Mrs. Baca of Belen, NM glanced up at the window that had recently been installed in the attic of her family's house and noticed "an image of Christ ascending into heaven" on the windowpane. [miracles of intervention blog
Soon thousands of people were flocking to see the "miracle window". The Christ figure could only be seen during daylight, and only from the ground. If you stood in the attic, the window looked perfectly transparent.
The image survived attempts to clean the window, even when it was cleaned with gasoline.
But puzzlingly, the image resisted being photographed. Many tried, but only one person, Fernando Gabaldon, succeeded in getting a shot of it. He then printed the image on postcards that he sold for 25 cents each.
The window is back in the news
because it's recently been acquired by the Harvey House Museum in Belen and will be on display on Dec. 21 and 22.
