Conical Mirror Anamorphosis: Chair.
Place and Year: [Dutch?, circa 1800].
Technique: Pen, pencil & Water-Colour on paper, originally mounted on card (Very Good, slightly dusty and stained) 34 x 34 cm (13.4 x 13.4 inches).
This stunning hand-drawn anamorphosis showcases a wooden chair on black and white tiles.
Anamorphosis, deriving from the Greek prefix ana‑, meaning back or again, and the word morphe, meaning shape or form, is a distorted projection or perspective requiring the viewer to use special devices or occupy a specific vantage point, or both to reconstitute the image. In this case the viewer needs to place a conical mirror in the middle circle in order to get an image of a chair and tiles, when looking at the middle point from above.
The drawing was probably made in the Netherlands around 1800 or at the end of the 18th century.
