[New York], 1973, pp. 127–32, no. 14, ill. p. 129 (color), figs. 1–4 (details), accepts the traditional identification of the sitter; relates the painting to a type of military portrait that first appeared in Italy during the mid-sixteenth century; notes that "the wig and greatcoat are actually part of the 'grand habit', or formal attire, worn in the early eighteenth century," and that the helmet and breastplate should be viewed as allegorical attributes; suggests that the armor belonged to Largillierre himself, as it reappears in three near-contemporary portraits by him.
