Mario Labò in Allgemeines Lexikon der bildenden Künstler. Ed. Hans Vollmer. Vol. 26, Leipzig, 1932, p. 201, lists it with the works of Panini, as "Cardinal de Polignac in Saint Peter's".
Harry B. Wehle. The Metropolitan Museum of Art: A Catalogue of Italian, Spanish, and Byzantine Paintings. New York, 1940, pp. 270–71, ill., as painted for Cardinal de Polignac and from his collection; mentions a larger version of the subject, dated 1730, in the Louvre, Paris.
Michael Levey. "Panini, St Peter's, and Cardinal de Polignac." Burlington Magazine 99 (February 1957), p. 54, dates it "not earlier than 1754" on the basis of the statues appearing in the niches; observes that the 1730 prototype in the Louvre was commissioned by Cardinal de Polignac and lists eighteen versions of the composition, including ours; among other later variants includes examples in the Landesgalerie, Hanover, the Ca'Rezzonico, Venice, and private collections formerly in Munich and London.
Ferdinando Arisi. Gian Paolo Panini. Piacenza, 1961, pp. 140, 209, no. 241, fig. 297, calls the Louvre example the first of the series, from which ours is substantially modified; accepts Levey's [see Ref. 1957] dating for our canvas of "not before 1754," and, since Cardinal de Polignac died in 1742, sees no reason to identify him in the composition; mentions preparatory drawings for our picture in the Gabinetto delle Stampe, Berlin (n. 17536) and the British Museum, London (inv. 789.197.b.5; fol. 12 and 101).
Richard P. Wunder. "L''Interno di S. Pietro' del Panini a Ca' Rezzonico." Bollettino dei musei civici veneziani 7 (1962), p. 12, dates it after 1754 based on its relationship to another version of the subject in the Museo Correr, Venice; notes that there are at least thirty versions of this subject that can fairly securely be attributed to the workshop of Panini, all of which differ in their figural groups, depiction of banners and the angle of projection of the architecture.
Federico Zeri and Elizabeth E. Gardner. Unpublished manuscript. [ca. 1970–80], note that this picture repeats a popular view of the interior of the basilica of Saint Peter's in Rome, which Panini executed at least twenty-three times for various patrons; explain that although Cardinal de Polignac commissioned and is portrayed in the primary version of 1730, the figures of a cardinal and his retinue in the other variants should be regarded as generic types; date it after 1754, since the statues of Saint Theresa of Avila and of Saint Vincent de Paul represented in this work were erected in that year; note that even though some of the replicas reveal the hands of Panini's son Francesco and other pupils such as Antonio Joli and Hubert Robert, "there is no reason. . . for thinking that our canvas is a work of collaboration".
