Riefelbild
A Riefelbild or -Painting (also: corrugating image or -Painting , perspective double portrait or raster image ) is an image which consists of side by side placed cylinders is having a triangular base surface, being mapped to two side faces of the cylinder respectively, a different design; the third side surface is attached to a flat surface. This creates independent right and left views of the image.
Most of the previously known Riefel paintings date from the 18th century and can be found in churches, but portraits of married couples were also popular.
variants
- Prism images
- In the prismatic pictures created by Jean-Etienne Liotard , the cylinders painted on all three sides can be rotated so that three different motifs can be viewed. In outdoor advertising , a modern form of prismatic images is sometimes used, in which the prisms rotate automatically and periodically in order to change the subject after a certain period of time.
- Harp pictures
- These successors to the Riefel pictures, also known as strings , scenery or box pictures , mostly date from the 19th century. In this case , gut strings are tensioned in a picture frame at regular intervals, similar to a harp . The cut strips of the motif are attached to the left and right of the strings so that two different motifs can be seen when looking at them from an angle. In a possible extension, another painting is attached behind the frame, with a direct view from the front. Harp pictures were once widely distributed through sale at pilgrimage sites.
