Some mountain features seem innocuous: a shadow, a rocky indentation, a darker area. Yet, this type of detail is ideal for a hare to slip by undetected.
In this illustration, the artist uses the natural contrasts of the terrain to create a slender silhouette, almost sculpted from the stone. To spot it, you have to squint slightly: you can then make out two small, erect ears, embedded in the rock face. This trick works because our brain first imagines a hare in a meadow… not clinging to the mountainside!
Third appearance: an unexpected goose
Who would think to scan the clouds for an animal? And yet, the latest surprise guest is hiding where no one would spontaneously look. In this scene, the shape of a goose blends with the white masses of the sky and the clear lines of a rock near the summit.
The artist uses a delicate technique: the silhouette is sketched with almost imperceptible contours. By slightly changing one's angle of view—as if creating an optical illusion —a long, slender neck and a beak turned towards the valley appear. A discovery as subtle as it is unexpected!
