Ernst Emmerling. Pompeo Batoni: Sein Leben und Werk. Darmstadt, 1932, pp. 109–10, no. 66, as "Portrait of a Gentleman"; comments that while the picture was previously ascribed to Drouais, it is now attributed to Batoni by Voss; notes that the Antinous relief in the Villa Albani (now Villa Torlonia) and a statue of Athena are represented among the objects on the table.

Federico Zeri. Letter. September 6, 1953, calls it a typical work of Batoni's Roman period, as indicated by the furniture; believes the sitter must be "a Roman prince, or more probably (as seems to suggest the guide to Rome) an English Lord in Grand Tour".
Anthony M. Clark. Letter to Theodore Rousseau. January 19, 1960, dates it about 1764, based on similarities to a portrait belonging to Lord Trevor, signed and dated 1764; notes that the table appears in a portrait of 1761 belonging to the Duke of Roxburghe (Floors Castle, Kelso) and that the chair reappears in a number of Batoni's portraits; believes an unfinished portrait in the Rhode Island School of Design represents the same individual; observes that Roberto Longhi, John Steegman, Ellis Waterhouse, and Luisa Marcucci have all verbally confirmed the attribution to Batoni.
Edith A. Standen. "The Grand Tour." Antiques 83 (June 1963), pp. 662–63, ill., as "not thought to represent an Englishman".
Federico Zeri and Elizabeth E. Gardner. Unpublished manuscript. [ca. 1970–80], as "Portrait of a Young Nobleman"; compare it to portraits by Batoni painted in the first half of the 1760s; identify the objects that appear in the picture and note that the same table and chair appear in other works by the artist; agree with Clark [Ref. 1960] that the same sitter is represented in the half-length portrait in the Rhode Island School of Design.

New York, 1982, p. 6, fig. 6, dates it to the early 1760s and notes that the sitter "has been thought French because of his costume"; considers the pose to reflect that of the Apollo Belevedere (Vatican, Rome); discusses the objects in the picture.
