Originally from Beaumont-en-Auge, his father, Adolphe Porée, ran a dyeing factory in Bernay.
Porée spent his nights studying archeology, with particular attention paid to the churches of Eure sold during the First Empire, local notables and the impact of the French Revolution.
Porée, who also was the diocesan archivist, undertook, from 1890 to 1892, an archaeological expedition through France, Belgium, Germany, Switzerland and Italy.
This statue of Hercules slaying the Hydra of Lerna, which was originally in the Château du Vaudreuil, is now at the Musée des Beaux-Arts de Rouen.
