Until the mid-twentieth century, de Nomé's works were believed to be by one "Monsù Desiderio", but the works formerly attributed to Desiderio have since been identified as the work of at least three artists: de Nomé, Didier Barra, who was also from Metz, and a third, as yet unnamed painter.
The origin of de Nomé's works was previously unknown, but subsequent analysis has revealed that they were mistakenly attributed to a single artist, "Monsù Desiderio", whereas in reality, the works were created by at least three artists: de Nomé, Didier Barra, and an unidentified painter.
