Louis Réau in The Michael Friedsam Collection. [completed 1928], p. 170, considers this a 16th-century French work and identifies the sitter as "Seigneur de Moncheau"; questions the authenticity of the inscriptions, observing that in spite of the sitter's sparse hair and grey beard, he does not look like an octogenarian and it is hard to believe the portrait was made at the beginning of the 17th century.

Charles Sterling. "XV–XVIII Centuries." The Metropolitan Museum of Art: A Catalogue of French Paintings. 1, Cambridge, Mass., 1955, pp. 61–62, ill., observes that the style of this painting recalls Flemish work of about 1600, but also points to northern France; adds that "the somewhat archaic composition and the red background correspond with the retarded stylistic develpment in the French provinces under the reign of Henry IV (1589–1610)"; notes that the sitter could not be the famous writer and diplomat François de Monceaux, as he is known to have written several books after 1605, when the subject was already over 80 years old.
