An early ad read, "THE MIRROSCOPE IS A PROJECTOR ALSO CALLED AN EPISCOPE OR A MAGIC LANTERN. IT HAS A LIGHT BULB THAT ILLUMINATES THE OBJECT TO BE PROJECTED AND REFLECTS IT THROUGH THE LENS ONTO A WALL OR SCREEN. YOU CAN SHOW PHOTOS OR OTHER PAPERS. YOU FOCUS IT BY MOVING THE LENS TUBE IN AND OUT."

  Aphengescope. Carte-de-Visite episcope c. 1880, especially used for projecting carte-de-visites, card size 6 x 10 cm.
Unmarked brass lens with rack-and-pinion focussing. The episcope itself is sometimes unmarked, sometimes marked by a white shield at the front 'Patent Aphengescope'.
The Aphengescope is also known as Mégascope.
In 1880/90 Alfred Molteni writes in his book 'Instructions Pratiques sur l’emploi des Appareils de Projection': 'For the projection of photographic card-de-visites (very popular in the years 1860), it is not necessary to have a special device. We use a small mégascope, known in the trade under the name of 'APHENGOSCOPE' (English APHENGESCOPE). It consists of a 10 cm square mahogany box that fits on the front of the first magic lantern from which the objective is removed. The light is concentrated on photography by the condenser, and the target placed at the image on the screen is 45 °. However documents to darker tones reflect too little light to give bright images on the screen.

To illuminate more strongly certain documents, it uses an double APHENGOSCOPE (or room Megascopique) to enjoy the light from two lanterns, through circular openings on each side of the goal. At the rear, two hinged doors, vertical or horizontal depending on the model, are used to project the cartes-de-visites alternatively and continuously.

It is with a device of this kind, and with two burners light, together giving a light equivalent to that of 500 candles, we (Alfred Molteni) have projected, in the lessons of Mr. Dr. Bouchut, the coloured boards of his magnificent "Atlas of medical ophthalmoscopy and cerebroscopie" (J.. Baillière and sons, Paris, 1876).
 However some do not seem to be of this opinion: "The Lantern and how to use it" by C. GOODWIN NORTON c Hazell, Watson ltd London 1901 Viney: There are several supplements to the ordinary projection lantern that the lanternist is attempting to purchase, usually due to the insistent demonstration of a merchant who has probably never seen the particular device in use. Among these, there are the APHENGESCOPE, an accessory intended to show opaque objects. It is not a practical device, because it is much better and easier to have the opaque object drew or photographed and then project it as a simple transparent view. In this case the light goes through the view and gives the screen a very bright image while with the APHENGESCOPE the light is reflected by the object, and this little light reaches the screen without any brightness.

Wide spread plastic episcope from the 1950s, made by DUX, Germany, intended to be placed upon a magazine or postcard and for that reason equipped with a handy handle at one side).
 
This simple episcope is also created by Dux. This time not in the well-known gray plastic design, but made of thick cardboard and painted with red hammered lacquer. For focussing the lens must manually been pushed in and out. This version was probably released shortly after World War II, when there was not enough material for a better implementation.




First card of a set of eight, telling the story of an odd pelican.

Around 1900 Butcher & Sons released sets of 'Primus Projection Post Cards' for episcopic projection. The pictures on these cards are the same as used on the glass lantern slides of their famous Primus Junior Lecturer Series. The cards are reverse-printed as the image was reversed on projection. Size is 3 1/2" x 5 1/2" (9 x 14 cm).
