Pierre-Jacques Gaultier is not listed in Tooley’s “Dictionary of Mapmakers” but has been traced in Benezit. He is recorded as an engraver born in Paris who worked in Naples. He worked normally on historical subjects and died in Parma. This finely engraved map of the Bay of Naples was published in ‘Le pitture antiche d’Ercolano e contorni incise con qualche spiegazione Antichita di Ercolano’, one of the finest archaological works of the century. It appeared in eight volumes over several years and was put together by the Accademia Ercolanese. Benezit “Dictionnaire des Peintres Sculpteurs Dessinateurs et Graveurs”.
