Antonio Isopi (5 February 1758 – 3 October 1833) was a Roman sculptor of Classicism mainly working at the court of the Dukes (later Kings) of Württemberg. Antonio Aloysius Petrus Isopi first lived and worked in his home city as a sculptor and soon specialized on restoring antique pieces of art. The iron cast Württemberg heraldic animals lion and hart – still to be seen in front of Stuttgart’s New Castle – are one of his major works.
