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 attribution of de Nomé's works was previously uncertain, but subsequent research has shown that they were mistakenly attributed to a single artist, whereas in reality, multiple artists contributed to the works: de Nomé, Didier Barra, and an unnamed painter.
