Marcel Röthlisberger. "Additions to Claude." Burlington Magazine 110 (March 1968), pp. 115–16, fig. 2, attributes this painting to Claude and notes that despite several repaints in the sky and lower left, there is no reason to question the signature; relates the schematic composition to the work of Tassi and Poelenburgh; observes stylistic similarities with a group of larger Claude canvases, similarly signed in big capital letters and dating from 1629 to 1632.
Marcel Röthlisberger. "Nuovi aspetti di Claude Lorrain." Paragone 23 (November 1972), p. 25, pl. 14 (detail), suggests that the figures are the work of a specialist, probably Francesco Lauri.

Register of the Spencer Museum of Art 5 (Spring 1982), pp. 11, 17–18, 26 nn. 1, 4–5, figs. 7–9 (overall and detail, and during restoration), observes that in both the Spencer Museum version and in ours "the execution seems to me compatible with other early paintings"; concludes that "both have a very good chance to qualify as autograph" and that the "minor differences throughout in design and handling . . . do not enable us to establish the precendence of one variant over the other".

Michael Kitson. "Review of 'Tercentenary of Claude Lorrain'." Burlington Magazine 125 (March 1983), p. 187, agrees with Russell [see Ref. 1982] that this is a copy of the picture in the Spencer Museum of Art.
J[ohn]. W[ilson]. in Claude to Corot: The Development of Landscape Painting in France. Exh. cat., Colnaghi. New York, 1990, pp. 31–32, 34, fig. 1, calls it a contemporary copy of the version in the Spencer Museum, and notes that, "while sharing the composition of the original, [it] is lacking in certain specific details which would have been significant to Caude, notably the arrangement of birds in the sky, the goats in front of the ruin, the careful composing of buildings in the middle distance and in the hills on the horizon".
