Bertrand Talabardon and Bertrand Gautier. Le paysage français de Valenciennes à Bonington. Exh. cat., Talabardon & Gautier. Paris, 2002, unpaginated, no. 9, ill. (color), identify the motif as Monte Valerio, Rome, based on comparison with two oil sketches thus inscribed (Musée Granet, Aix-en-Provence, inv. 849-1-G.148 and 849-1-G.82); state that in such works Granet transcends the lexicon for landscape sketching established by Pierre-Henri de Valenciennes; note that the application of paint here coincides with Granet's initial forays into watercolor, which supports the date of 1804 inscribed on the verso.
