A glass lantern slide numbered 92 produced by Newton & Co which formed part of a series titled "Persia" which consisted of 103 glass slides. The photographs were attributed to Reverend C. H. Stileman. However, a number were taken by other photographers, such as Antoin Sevruguin and Ernest Hoeltzer. Reverend C. H. Stileman went on to become the Anglican Bishop of Persia in 1912.
Newton & Co catalogue of lantern slides, part II, 1911/1912
The image is reproduced on page 175 of Volume IV of “Du Khorassan au pays des Backhtiaris: trois mois de voyage en Perse” by Henry-Rene D’Allemagne published in 1911 by Hachette, Paris, France. The image is titled "Route taillee dans le roc". However, the two individuals with bicycles in the original image have been removed. Of interest, is that the magic lantern slides in the Nelson collection are each accompanied with a glass negative slide. The glass negative slide associated with this particular image also has the two individuals with bicycles removed from the image. This raises the possibility that the slides may have been used by Henry-Rene D’Allemagne, as this is the case with at least two other images.
