Above A damaged, 19th century Swiss photograph of a small child in a white hat (just left of center) seated on her father's lap, with her mother standing at the right. Circumstances are such that, at first glance, some viewers interpret the child's face as the eye of a profile of Christ, facing left.
Like the man in the moon, or a face in the clouds, this is an example of seeing apparently meaningful forms in random or accidental formations, called pareidolia. Unless of course (as might well be), the photograph has been altered, to increase the likelihood of seeing the figure.
As I discuss in a new online 25-minute video talk, titled Art, Embedded Figures, and Camouflage, there is a long tradition of the purposeful insertion of embedded figures (or, as they are sometimes called, camouflaged figures), in picture puzzles and works of art. Here's a brief excerpt from the video narration, followed by the two advertising diagrams that it describes—
Not surprisingly, embedded figures have also been used in advertising. During World War I, for example, at the height of the public’s interest in dazzle-painted ship camouflage, this unidentified diagram was published in a British magazine, repeatedly—on the same page, in the same location—for several weeks. It simply read: A dazzle advertisement of a dazzling discovery. That was all that anyone knew.
And then, suddenly, in the last week of the ad campaign, an “embedded figure” solution appeared, also on the same page, same place. Camouflage has its uses, it said, but Firth’s Stainless Steel needs no protective covering.
