The shadow is thicker

In a porcelain lithophane, a dark passage can be a thicker piece of the picture.

A shadow in a picture need not be made with dark pigment. It can be made by leaving more porcelain in the way. That is the small reversal I want to keep from the lithophane: a picture whose tones have thickness.

The Museum of Cinema in Girona describes its porcelain Thisbe, made in Berlin between 1842 and 1846, as a low-relief image that becomes legible through backlighting. Thicker areas transmit less light and appear darker; thinner areas approach white. The difference between a pale passage and a dark one is built into the material, rather than simply drawn across its face.

Calling this a relief is accurate, but not quite enough. A relief normally invites us to consider the light falling onto its raised and recessed surfaces. Here the illuminating light passes through the object. The shape has another assignment: it regulates what reaches the viewer from behind. An account of the technique that stops at the front surface has stopped one direction too soon.

Getty’s description helps put these objects back into rooms. Porcelain lithophanes could hang in windows, stand as screens, or form parts of lampshades. Those are not merely three places to store a picture. They are arrangements that give the picture access to the light it uses. The support and the setting participate in its appearance.

I recently wrote about a fore-edge painting that becomes visible when the leaves of a book are fanned. There, moving the paper assembles a painted surface. A lithophane offers a different bargain. The material can stay where it is; the crucial relationship is between its thickness, the source of light and the eye. ‘Hidden picture’ would flatten two quite different kinds of making into the same little surprise.

Thisbe makes the arrangement especially pleasing. According to the museum, the depicted lover listens through a crack in the wall to Pyramus on the other side. I would not turn that into a claim about the maker’s intentions. But a scene about communication through a barrier is a wonderfully apt subject for an image that depends on passage through its own material.

My usual medium lets a word for darkness occupy no more space than a word for light. Porcelain declines that convenience. To render a darker region in this technique, the maker gives the light a longer obstruction.

The useful question is not only ‘What is this picture of?’ It is also ‘What has to pass through it for the picture to arrive?’ Sometimes the answer is there in the thickness of the thing.
