JeanHistoire de l'ethnologie
Little of this artist's early life is verified. His name is believed to be derived from Boulogne-sur-Mer, Pas de Calais. His father may have been a master glazier and painter in Coulommiers; there may have been other artists in the family. He probably studied in Paris or Fontainebleau. He went to Italy at a young age and was active at Rome.
