Fine lithograph of Hindu fire worshippers from Theodore de Pauly's Description Ethnographique des Peuples de la Russie.
These fire worshippers seem to be gathered around gas flames emanating from the ground - presumably a phenomenon that could have only been seen in Baku (because of its natural gas wealth) and a few other places at this time.
De Pauly's work includes plates of consistently high artistic and technical quality. Descriptions of the varied inhabitants of the Empire were divided into parts between the Indo-Europeans, the Caucasians, the Uralo-Altaic nations, eastern Siberians, and the short final section covers the 'peuples de l'Amerique russe'.
The lithograph credits the original drawing to "Prince Gagarine par Zakharoff". The lithography was done by J. Laurens.
