Max J. Friedländer. Letter to Herr Loebl [at Kleinberger & Co.]. December 11, 1923, ascribes these altarwings to the Master of the Saint Ursula Legend, about 1480; notes that a panel apparently from Rogier's hand with the same composition as our right wing, and nearly life-size figures, is probably still with Duveen [now National Gallery, Washington].

Max J. Friedländer in The Michael Friedsam Collection. [completed 1928], p. 142, as from the Marchese Ferroni collection, Florence; notes that the composition of the right wing can be traced back to Rogier.

Martin Davies. National Gallery Catalogues: Early Netherlandish School. London, 1945, pp. 115–16 n. 2, notes that its design is similar to that of the "Christ Appearing to the Virgin" by a follower of Rogier in the National Gallery, London.

Harry B. Wehle and Margaretta Salinger. The Metropolitan Museum of Art: A Catalogue of Early Flemish, Dutch and German Paintings. New York, 1947, pp. 76–77, ill., suppose that the name of the donor figure was Paul as he is shown here under the protection of Saint Paul the Apostle.
Erwin Panofsky. Early Netherlandish Painting: Its Origins and Character. Cambridge, Mass., 1953, p. 463 n. 4 (to p. 263), mentions the right wing as an example of copies and variations of Rogier's composition of Christ Appearing to His Mother in the Granada-Miraflores altarpieces (including panel in MMA, 22.60.58).

Erik Larsen. Les primitifs flamands au Musée Metropolitain de New York. Utrecht, 1960, pp. 76, 120–21, attributes them to an anonymous Bruges painter from the end of the 15th century; finds the right wing superior in quality and doubts that the two panels were the work of the same hand.
Colin Eisler. "Erik Larsen, Les primitifs flamands au Musée Metropolitain de New York, 1960." Art Bulletin 46 (March 1964), p. 100, rejects Larsen's excision of these paintings from the oeuvre of the Master of Saint Ursula, noting that the artist "often worked hastily and many of his depictions of donors seem to have been added after the general composition was completed".
Georges Marlier. "Le Maître de la Légende de sainte Ursule." Jaarboek / Koninklijk Museum voor Schone Kunsten (1964), p. 37, no. 28, lists it with works whose attributions are open to discussion.

Michael Rohlmann Universität Köln. Auftragskunst und Sammlerbild: Altniederländische Tafelmalerei im Florenz des Quattrocento. Alfter, Germany, 1994, p. 70, reconstructs an altarpiece with the Virgin and Child Enthroned in the Cherbourg Museum as the central panel, our panels as the interior wings, and two grisaille panels in the Museo Bandini, Fiesole, as the exterior wings; observes that not only do the wings have a Florentine provenance, but the coat of arms in the central panel are also Florentine, and identical with those in a Memling panel with the Virgin and Child Enthroned in the Uffizi, Florence.
Michael Rohlmann. "Memling's 'Pagagnotti Triptych'." Burlington Magazine 137 (July 1995), pp. 439–41, ill. (reconstruction view of interior [including our panels] and exterior of triptych), identifies the coats of arms in the Cherbourg panel and in Memling's Virgin and Child in the Uffizi as those of the Pagagnotti family of Florence and notes that Paolo Pagagnotti, "one of many widely-traveled Florentine merchants of the period" was clearly the patron of the triptych to which our interior wings belong; concludes that the Memling triptych was commissioned by his relative Benedetto Pagagnotti.
