W. v. Seidlitz in Allgemeines Künstler-lexikon. Ed. Julius Meyer et al. Vol. 3, Leipzig, 1885, p. 313, as by Beham, in a Berlin private collection; remarks that von Eck appears younger here than he does in Beham's print; notes that the painting is abraded.
Max J. Friedländer. "Altdeutsche Gemälde in der Sammlung des Freiherrn von Lotzbeck in München." Repertorium für Kunstwissenschaft 18 (1895), p. 274, questions the attribution to Beham, without having seen the painting [see Ref. Friedländer 1912].

Gustav Pauli. "Barthel Beham in seiner künstlerischen Entwickelung." Graphischen Künste 28 (1905), pp. 41, 44, considers it one of Beham's best portrait paintings; remarks that it corresponds so closely to the 1527 print that it can be dated to the same year and is surely by the same hand; notes that von Eck appears older in the engraving due to strong contrasts of light and shadow in the modeling.
Karl Woermann. Wissenschaftl. Verzeichnis der älteren Gemälde der Galerie Weber in Hamburg. 2nd ed. Dresden, 1907, p. 54, no. 57, lists it as "Portrait of a Man" by Beham, but questions the attribution, commenting that it may continue under his name until a different attribution is found.

Emil Waldmann. Die Nürnberger Kleinmeister. Leipzig, 1910, p. 77, calls Beham's portraits his strongest works, mentioning this one in particular; notes, however, that von Eck was such a striking character that a lesser artist would probably have succeeded in producing an arresting portrait of him.

A. L. Mayer. "Barthel Beham als Bildnismaler." Pantheon 11 (January–June 1933), p. 1, observes a "striving for monumentality" in this portrait which finds its ultimate expression in Beham's portrait of Ruprecht Stüpf [Museo Thyssen-Bornemisza, Madrid].

Baltimore, 1969, pp. 231–32, pl. 215, call it Beham's earliest "dated" portrait and note that when it was painted Durer had just made his engraving of Erasmus, which directly effected Beham's [first state] of the print.

Isolde Lübbeke. Early German Painting, 1350–1550: The Thyssen-Bornemisza Collection. London, 1991, p. 404, calls it the first portrait executed by Beham in Munich, which prompted portrait commissions from Duke Wilhelm IV and "the patriciate".

Christiane Andersson. Letter to Katharine Baetjer. October 27, 1996, observes that the sitter's cross-armed pose—which seems very informal compared with other German Renaissance portraits—and his absence of outer wear, suggest a private function for the portrait.
Alison Stewart in The Dictionary of Art. Ed. Jane Turner. Vol. 3, New York, 1996, p. 507, remarks that in this picture Beham used the Italianate half-length format of Dürer's engraving of Erasmus "reputedly for the first time in a German painted portrait"; calls it typical of his portraits of the middle and upper classes.
Nadine M. Orenstein in "The Print in the North: The Age of Albrecht Dürer and Lucas van Leyden." Metropolitan Museum of Art Bulletin 54 (Spring 1997), p. 49, notes that this painting and the first state of the print were probably based on a now-lost drawing.
Kurt Löcher. Barthel Beham: Ein Maler aus dem Dürerkreis. Munich, 1999, pp. 71–72, 187–88, no. 6, fig. 69 (color), maintains that this painting is based on the first state of the print [see Ref. Löcher 1967], suggesting that the position of the sitter was reversed to face a pendant portrait of von Eck's wife; finds the painting's execution unconvincing and questions the attribution to Beham.
