A small, unnamed ~18th century album of pencil and watercolour sketches is hosted online among the prints and photographs in Gallica, the digitised collection at Bibliothèque nationale de France.
The subjects - Mughal emperors and Hindu gods - originate in the Indian subcontinent, and the BNF assesses the date range of the drawings at between the early 1600s and late 1700s (ie. they don't know). It seems likely that more than one artist was involved and a few of the works were never taken much further than the preliminary sketch stage. About the only thing known for certain is that this album was once owned by 19th century French polymath Egyptologist, Émile Prisse d'Avennes, whose works have been featured here previously: Classical Egypt & L'Art Arabe.
