Sánchez Cantón, ed., vol. 4, Madrid, 1936, pp. 167–68; 1796 ed., pp. 501–2], states that Velázquez painted his slave Juan de Pareja to prepare himself for painting Pope Innocent X; cites "Andrés Esmit" [Andreas Schmidt], a Flemish painter in Rome at the time, who described an exhibition of paintings by ancient and modern masters in the rotunda [of the Pantheon] on the Feast of Saint Joseph, in which this portrait excited great admiration: all the painters of different nationalities agreed that whereas all the other works looked like painting, this alone was truth; claims that as a result Velázquez was admitted to the Roman Academy in 1650.

Elizabeth du Gué Trapier. Velázquez. New York, 1948, pp. 302–3, 309, figs. 195–96 (overall and detail), mentions only the Radnor portrait and calls it Velázquez's original; notes that in a letter dated May 12, 1630, a "Juan de Pareja" wrote to the procurator of Seville stating that he held the office of painter (an office not permitted to slaves) and requested permission to go to Madrid to study painting; concludes, on this basis, that Pareja was Velázquez's studio assistant, not his slave as stated by Palomino [Ref. 1724].
William E. Suida. A Catalogue of Paintings in the John & Mable Ringling Museum of Art. Sarasota, 1949, p. 279, calls the Radnor picture the original and the Castle Howard version a good replica.

New York, 1952, pp. 13–14, calls the version in the Hispanic Society a copy, possibly made by Juan de Pareja in Velázquez's studio, and under his direction; suggests their version was the portrait in the collection of Cardinal Trajano de Acquaviva in Rome in the 18th century.

Enriqueta Harris. "Velázquez en Roma." Archivo español de arte 31 (July–September 1958), pp. 189–91, notes that Velázquez was elected to Rome's Accademia di S. Luca in January 1650, but the annual exhibition at the Pantheon on the feast day of Saint Joseph did not occur until March 19, 1650; thus Palomino's report that the artist's election to the Academy resulted from the impression this portrait created at the Pantheon cannot be correct; notes that these annual exhibitions were actually mounted by the Congregazióne dei Virtuosi and provides contemporary evidence that Velázquez was also a member of this group prior to March 19; states that in every other respect Palomino's description of the circumstances under which this portrait was painted are reliable.
Martin Soria in George Kubler and Martin Soria. Art and Architecture in Spain and Portugal and their American Dominions, 1500 to 1800. Baltimore, 1959, p. 265, calls it firmer and less sketchy than the other portraits Velázquez painted in Rome, which he describes as "Titianesque".
Francis Haskell. "Art Exhibitions in XVII Century Rome." Studi Secenteschi 62 (1960), p. 111, cites Velázquez as the first painter we know of who used the Pantheon exhibitions to draw attention to himself beyond papal and artistic circles; notes that the artist was already a member of the Accademia di S. Luca and of the Congregazione dei Virtuosi when this portrait was exhibited.

Metropolitan Museum of Art Bulletin 51 (Winter 1993/94), pp. 26–31, fig. 1 (color), believes the finished canvas remained on its original support for a long time before it was folded over; refutes Pope-Hennessy's [see Ref. 1991] belief that the canvas had been folded over by Velázquez himself in order to center the figure; points out that the dimensions of the copy in the Hispanic Society correspond to those of the original after the canvas was folded, probably when it entered the collection of the earl of Radnor; mentions the copy sold at Christie's in 1992—the only extant copy that matches our painting exactly in size and composition—as evidence that the composition was always intended to be left of center.

Farnham, England, 2009, pp. 111, 113, fig. 4.6 (color), discusses the hierarchy of genres and Velázquez's decision to present himself as a portrait rather than a history painter in his second visit to Rome; notes that portraits were seen as one notch above genre painting, since their subjects were so often of noble birth, but in the case of his portrait of Pareja, Velázquez "emphatically removed the nobility of the subject from the equation and thereby asserted the nobility of portraiture as portraiture," a clear challenge to the accepted hierarchy.
