^The subject of this portrait was identified as Louis Le Vau in 1955 by Albert Laprade, who recognized the plan as that of the southwest corner of the old Louvre, that is the Bathing 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 at the north end of the Louvre's Petite Galerie (see Galerie d'Apollon), constructed after the fire of 1 February 1661 (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 Christophe Hardouin disputed Laprade's attribution in an unpublished thesis for the University of Paris and identified the painting as Pierre Rabon's presentation piece before the Academy on 3 July 1660, which portrayed Antoine de Ratabon (1617–1670), Surintendant des Bâtiments (see Thierry Bajou; also Hilary Ballon 1999, p. 201, note 8, who was unable to examine the thesis but cites Bajou). Bajou comments that the "building plan and the facade therefore correspond to projects and not to completed buildings. It is unfortunately, just as impossible to confirm this identification, by comparing the sitter's features with those in other painted, sculpted or engraved portraits."
