Paul Ganz. Die Handzeichnungen Hans Holbeins des Jüngeren. Lieferung 31–35, Berlin, [1911–26], under text for drawing no. XXXIII 10 (the Windsor drawing), identifies the drawing in the Royal Library, Windsor Castle [London], as a study for our roundel, then in the H. M. Clark collection; describes the sitter as a twenty-eight-year-old nobleman.
Paul Ganz. "Ein unbekanntes Herrenbildnis von Hans Holbein d. J." Jahrbuch fuer Kunst und Kunstpflege in der Schweiz (1921–24), pp. 294–96, pl. 7, discusses this roundel, in the Sachs collection, as an adaptation by Holbein of the portrait miniature, and places it chronologically between "The Ambassadors" [National Gallery, London] and the portrait of Sir Richard Southwell [Uffizi, Florence]; based on his costume, identifies the sitter as a French nobleman and suggests he may be one of Jean de Dinteville's brothers; asserts that our portrait roundel, like the roundel of Edward VII in the collection of Viscount Lee of Fareham [MMA 49.7.31], is 30 cm in diameter and painted on oak prepared with a chalk ground; notes that the finished portrait follows the preparatory drawing in Windsor Castle line for line.

Städel-Jahrbuch 7–8 (1932), pp. 125–27, fig. 89, states that this is Holbein's earliest large roundel; notes that the rectangular form of the preliminary drawing leads one to wonder if this portrait was originally conceived as a roundel.

K. T. Parker. The Drawings of Hans Holbein in the Collection of His Majesty the King at Windsor Castle. London, 1945, p. 45, fig. 15, under no. 33, remarks that the painting shows the drawing to have been cut at the right and adds that although the drawing is "rather rubbed" and retouched in black chalk, "the penwork is of good quality and may be accepted as Holbein's"; rejects Ganz's view [Ref. 1921–24] that the sitter is a Frenchman, perhaps one of the Dinteville brothers, observing that there is no evidence to support either contention.

Art Bulletin 31 (June 1949), p. 143, observes that this portrait "while surely reflecting an original by Holbein, seems to be too poor for a product of Holbein's own brush"; calls it "an old copy of a lost original".
Paul Ganz. The Paintings of Hans Holbein. London, 1950, p. 246, no. 86, pl. 128, identifies the sitter as "a Frenchman, probably a member of the French embassy in London".

Susan Foister. Drawings by Holbein from the Royal Library Windsor Castle. London, 1983, pp. 18–19, 21, 42, under no. 33, fig. 35, attributes it to Holbein and notes that in this, as in other cases, measurements from the painting and corresponding drawing indicate some form of mechanical transfer.
John Rowlands. Holbein: The Paintings of Hans Holbein the Younger. Oxford, 1985, pp. 114, 232, no. R. 22, ill., comments on the marking of the outline of this portrait, comparing it with the portrait of Jane Seymour in the Hague [Mauritshuis], in which the figure is painted in "a slightly sunken area on the panel"; attributes the Hague picture to a close follower of Holbein and ours to a follower very likely trained in Holbein's studio.
Jane Roberts. Drawings by Holbein from the Court of Henry VIII. Exh. cat., Art Gallery of Ontario, Toronto. [New York], 1988, p. 70, ill., attributes the painting to Holbein, but quotes a written communication from Maryan Ainsworth of 1986 ascribing the painting to Holbein's workshop, as there is "a more extensive under-drawing in brush than is normally found in works by the artist (except those from the very end of his career)".
Maryan W. Ainsworth. "Northern Renaissance Drawings and Underdrawings: A Proposed Method of Study." Master Drawings 27 (Spring 1989), pp. 17–18, figs. 17, 19 (infrared reflectogram), attributes the Windsor Castle drawing to Holbein but finds the "wooden, lifeless character" of the painting indicative of a workshop product; notes that the use of an "interleafing carbon-coated sheet [for transfer] is strongly suggested by blackened lines on the back of the drawing, which are confined to countours reinforced on the front".

Mike Gray. Sutton House: An Illustrated Souvenir. rev. ed. London, 1997, p. 6 [mentions only the drawing], tentatively identifies the Holbein drawing on which our portrait is based as a likeness of Ralph Sadleir [or Sadler]; discusses the history of Sutton House, built by Sadler, Secretary of State to Henry VIII and diplomat in the service of subsequent Tudor rulers.
Alastair Laing. E-mail to Maryan Ainsworth. December 19, 2003, reports that the identification of our portrait as that of Sir Ralph Sadler is speculative, but not implausible, adding that the date of our painting is the date that he built Sutton House; observes that the only certain likeness of him is that on his tomb in Sutton church, Hertfordshire, which shows him as an old man; adds that there is another, full length, portrait of him with a hawk on his wrist, which survives only in a schematic copy.

Susan Foister. Holbein in England. Exh. cat., Tate Britain. London, 2006, p. 114, no. 125, ill., as "produced under Holbein's supervision but by an unidentified assistant who must have been working with him in England"; notes that the dates [date and age] inscribed on our portrait "have plausibly suggested the sitter might be Sir Ralph Sadler (1507–1587), a protégé of Cromwell who in 1535 became clerk of the hanaper of chancery; although there are other possible candidates whose date of birth would fit those on the painting, the clothing of the sitter suggests he was probably not of noble birth".
