"Alloïs d'Herculais." Annuaire de la noblesse de France 31 (1875), pp. 121–22, states that the portrait belonged to the sitter's grandson Antoine-Marie-Jules Alloïs, comte d'Herculais, who in his will expressed the wish that it remain in the family; adds that after an ownership dispute, Jules Kunckel was declared the rightful owner.

The Wrightsman Collection. 5, [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 18th century," and that the helmet and breastplate should be viewed as allegorical attributes; questions whether the sitter actually owned the armor, as it reappears in three near-contemporary portraits by Largillierre.
