Fabienne Xavière Sturm. Letter to Katharine Baetjer. December 11, 1995, with Hans Boeckh, suggests that it is an early work of the Geneva enameler Louis Ami Arlaud, called Arlaud-Jurine (1751–1829), painted between 1780 and 1785.
Graham Reynolds with the assistance of Katharine Baetjer. European Miniatures in The Metropolitan Museum of Art. Exh. cat., The Metropolitan Museum of Art. New York, 1996, p. 194, no. 276, ill. p. 195, date it about 1780 and note that "the handling, which is sfumato and without strong accents, appears to have more affinity with the style of the followers of Jean Étienne Liotard (1702–1789) in Switzerland than with the French artist Weyler".
Haydn Williams. Letter. January 4, 1996, states that it "looks quite like the work of Jean Théodore Perrache".
