For another painting of the subject by Hendrik van Balen and Jan Brueghel the Younger in which the figure of the Virgin is related to that in the present picture, see K. Ertz, Jan Breughel der Jngere, Freren, 1984, pp. 311-12, no. 142, colour pl. 27; that picture is, however, much smaller, measuring only 48 x 38cm.
