5. Gettens and Stout 1942, pp. 173–4. In England the colour maker George Field was also making the colour, and his journal entry for 1815 gives a recipe for chromium oxide. Most assume that the green supplied by Field from 1815 was of the opaque variety, but this cannot be certain, as he did not make any chemical distinction between the opaque and transparent green.  In his Chromatography, an account of pigments available at the time, he talks of a true chrome green, ‘of various degrees of transparency or opacity’.

10. Alfred Robaut, Documents sur Corot, Bibliothèque Nationale de France, Cabinet des Estampes,  Yb3 949, II, p. 15. Quoted in Roquebert 1998, p. 90. While acknowledging that on occasion Corot did make use of certain greens, for example vert Veronèse and vert éméraude, Roquebert repeats this in her essay ‘La technique de Corot’ in Madrid/Ferrara 2005–6, pp. 57–71, French translation, pp. 343–7, Italian edn, pp. 59–71, esp. pp. 66–7. In both essays she cites the findings of  J.- P. Rioux that Corot hardly ever used ready-made greens, backed up by R. Woudhuysen-Keller, J. Cuttle and Ch. Hurst, ‘Zwei Gemälde von Camille Corot. Gedanken zur Maltechnik und  zur Restaurierung’, Restauro, 1993, no. 3, pp. 306–15.


11. See Burmester and Denk 1999, p. 302.

12. Two later paintings in the collection where viridian has been found are NG 6439, Peasants under the Trees at Dawn,  and NG 6466, The Oak in the Valley, both of which are discussed below. At the same time Corot also created greens using a mixture of Prussian blue and chrome yellow, as in NG 2625, The Leaning Tree Trunk.


13. Corot returned to France via Venice. He was again in Italy in May – October 1834, and May – August 1843. 

14. Baehr made two further trips to Rome, in 1827–8 and 1834–5. There exists from the last trip a painting, Campagna Landscape, which also shows the aqueducts (Dresden, Gemäldegalerie Neue Meister, no. 2698).

15. See Jullien 1987, pp. 112–13, for a discussion of the view.  

16. See T. Ashby, The Aqueducts of Ancient Rome, ed. I. A. Richmond, Oxford 1935, p. 232.


17. In this view he is situated four kilometres from the Porta San Giovanni.


18. In this latter they are viewed from next to the tomb of Cecilia Metella. See P. Galassi, Corot in Italy, 1825–8, PhD thesis, Columbia University, 1986, p. 419, where he links R96 with R101 and R180, stating that two of them are copies of the third, but as he has not been to able to study them at first hand, is not able to say which is the original.

23. The compiler is grateful to Claire Bechu, Centre Historique des Archives Nationales, Paris, for this suggestion. Martin Davies identified Saint-Barbe as the Collège Sainte-Barbe in Paris, but was not able to find mention of Panis in either J. Quicherat, Histoire de Sainte-Barbe, Collège etc, Paris 1860/4, or in the Almanach Royal for that period. He is also not mentioned in E. Nouvel, Le Collège Sainte-Barbe: la vie d’un collège parisien de Charles VII à nos jours, Paris 1948. There is no mention of Panis among the college’s archives in the Sorbonne, which in fact date mostly from before the Revolution. The compiler is grateful to Jacqueline Artier, conservateur du service du livre ancien, Bibliothèque de la Sorbonne, for checking this.

25. Collection de M. Le Comte Armand Doria. Tome Premier, tableaux modernes. Préface et Catalogue analytique par M.L. Roger-Milès. Précédés d’un essai sur la Vie du Comte Armand Doria par M. Arsène Alexandre, Paris, Imprimerie Georges Petit, 1899. If indeed Corot simply lent the painting to Panis, then it would be plausible to suggest that Count Armand Doria, who was an important collector of Barbizon and Impressionist pictures and who invited artists to stay with him, bought this painting directly from Corot. Degas paid 1,150 francs for this painting. Information from L’Album Souvenir of the collection, which appeared a few months after the sale, conveyed by Comte Arnauld Doria in a letter of 20 April 1956 in the dossier. The National Gallery Library also holds an Album Souvenir, which records the price as 1,820 francs.


26. NG 3285 was one of seven paintings by Corot in Degas’s collection, six of which were landscapes, the seventh being a figure study of a woman. Although Degas was not alone in collecting Corots at this period, it was unusual to concentrate, as he did, on the artist’s early work. It has been noted that Degas might have been attracted to Corot’s Italian scenes because of their reminder of Degas’s own time in Italy in the 1850s, from where he wrote: ‘A feeling of antiquity survives in the countryside, that is wild, empty, cursed like the desert, with its great mountains carrying aqueducts and its herds of cattle spread far and wide. This is really beautiful, with the kind of beauty that is like a dream of antiquity.’ Quoted in A. Dumas, Degas as a Collector, exh. cat., National Gallery, London 1996, p. 36. It is probable that it was one of the `two small Views of Italy by Corot’ which hung in Degas’s bedroom. See P. Lafond, Degas, Paris 1918, pp. 177–21. Holmes writes that it was ‘the vivid little early landscape by Corot, which Degas kept hanging over his bed’.  C.J. Holmes, Self and Partners (Mostly Self), London 1936, p. 338.

For the Degas collection and sales see  London 1996, p. 36; New York 1997–8, Holmes 1936, pp. 336–42; D. Sutton, ‘The Degas Sales and England’, Burlington Magazine, April 1989, pp. 266–72; Anne Emberton, ‘Keynes and the Degas Sale’, History Today, January 1996, pp. 22–8. NG 3285 does not seem to have been considered the most important work by Corot in the collection, as The Limay Bridge was singled out by more commentators on the sale. However, Bouyer gives it this praise: ‘As for the Ruins of the Claudian Aqueduct, its pink patches in the harsh Roman countryside rendered in unusual greens, it is one of those loyal nature studies that justify Poussin’s bluish backgrounds and vast cloudy skies.’ See R. Bouyer, ‘Mouvement des arts: la Collection Edgar Degas’, La Chronique des Arts, March 1918, pp. 85–7, reprinted in Dumas, Tinterow et al., 1997–8, pp. 310–12.
