Maryan W. Ainsworth. "Northern Renaissance Drawings and Underdrawings: A Proposed Method of Study." Master Drawings 27 (Spring 1989), pp. 11, 36 n. 22, observes that it is not surprising that the Mourning Virgin has a pounced underdrawing, since many copies of this popular image were produced.

Catherine Johnston in Sorrowful Images: Early Netherlandish Devotional Diptychs. Exh. cat., National Gallery of Canada. Ottawa, 1999, unpaginated, fig. 4 (color), notes that in both the Chicago and Ottawa diptychs the fingers of the Virgin's hands have been lengthened, and that all subsequent workshop replicas "have been painted with long fingers in imitation of these two"; notes that in our panels, however, the fingers of the Virgin are shorter, "in the manner often encountered with Dieric the Elder"; ascribes both the London and Ottawa diptychs to the Workshop of Dieric Bouts, dating the latter 1485–95, and calls our diptych a Copy after Dieric Bouts, c. 1525.

Metropolitan Museum Journal 39 (2004), pp. 180–81, 221, 245, appendix 1A nos. 157–58, ill. p. 221 and fig. 37, remarks that these panels were exhibited in 1872 as from the school of Rogier van der Weyden, and, along with an Adoration of the Magi (71.100), were the only early pictures in the 1871 purchase; notes that in the 1872 catalogue Gauchez attributed them to two different painters of the school of Rogier van der Weyden, and based on this "rather perverse cataloguing," tentatively identifies them with two pictures sold at Hôtel Drouot, February 28–March 1, 1870, as lots 113 and 114.
