 Le Gros thrived on playful invention.When, some time between 1706 and 1715, he was asked by the Portuguese ambassador to add heads, hands and legs to a fragmented antique group of "Amor and Psyche", he deliberately turned the love story on its head and transformed it to the tale of "Caunus and Byblis" in which Caunus vehemently defends himself against the sexual advances of his sister.Le Gros' creation quickly became popular and triggered a rafter of drawings, reproductions and copies by for example Pompeo Batoni, Francesco Carradori, Martin Klauer and, best known of all, Laurent Delvaux who carved two marble versions.
