^According to Hilary Ballon (1999, p. 201, note 8), the subject of this portrait was identified as Louis Le Vau in 1955 by Albert Laprade, who identified the plan as that of the southwest corner of the old Louvre, that is the apartment of the Queen Mother Anne d'Autriche, remodeled by Le Vau in the summer of 1661, and the building illustrated in the background as the pavilion next to the Louvre's Petite Galerie (Galerie des peintures), designed by Le Vau, but destroyed by fire on 1 February 1661 and reconstructed a short time later (see also Laprade 1960, chapter 3, plate 1); Christophe Hardouin disputed Laprade's attribution in an unpublished thesis for the University of Paris and identified the subject as Antoine de Ratabon (1617–1670), Superintendant des Bâtiments. Ballon was unable to examine the thesis but cites Thierry Bajou, who discusses Hardouin's reattribution.
