BOREL, PETRUS, full name PIERRE JOSEPH BOREL D'HAUTERIVE (18o9-1859), French writer, was born at Lyons. His father had been ruined by taking part in the resistance offered by the Lyons royalists against the Convention, and Petrus Borel was educated in Paris to be an architect. He soon abandoned his profession to become one of the most violent partisans of the Romantic movement. His extravagant sentiments were illustrated in various volumes: Rhapsodies poems; Champavert, contes immoraux (1833) ; Madame Putiphar (1839), etc His works did not rescue him from poverty, but through the kindness of Theophile Gautier and Mme. de Girardin he obtained a small place in the civil service. He died at Mostaganem in Algeria. See Jules Clarctie, Petrus Borel, le Lycanthrope (i865) ; and Ch. Asselineau, Bibliographic romantique (1872).
