These wall lights evoke two distinct stylistic trends, that of the Régence with the stem and that of the Louis XVI style with the woman draped in antiquity. The assembling, the handling of the chiseling and the gilding allude to a production from the second half of the 18th century, though the model had traditionally been presented as Régence.
This assessment coincides perfectly with a very plausible comparison, that of a possible purchase by Madame Du Barry from the decorative arts dealer Simon-Philippe Poirier on 10 October 1770. A memoir by Simon-Philippe Poirier kept in the archives of Seine-et-Oise partly published by G. Wildenstein (op.cit.), explains that he supplied it to Madame Du Barry for Fontainebleau, « Une paire de bras à deux branches en bronze doré d’or moulu, model à figures et cornes d’abondance, cy 400 livres ».
Nevertheless, other possibilities are equally conceivable, since this model is found in the auction of 9 June 1777: « 151. Trois paires de bras à deux branches représentant des caryatides avec cornes d’abondance, le tout doré d’or moulu ».
An identical pair of wall-lights from Madame Danièle Ricard's collection was auctioned by Sotheby's in Paris on 14 September 2017, lot 83.
