The work refers to Paolo Saverio di Zinno , a sculptor from Campobasso who lived between 1718 and 1781 , who after a period of training in Naples disseminated the Molise and neighboring territories with devotional statues. The S. Giuseppe is dated to 1770 by the inscription on the base which dates back to 1848, and which until a few years ago was covered by a similar inscription affixed by the archpriest Serafino Sbarra in 1916, on the occasion of the restoration of the Church. The autography can be confirmed in some drawings of the Albino Library in Campobasso depicting St. Matthew, and in some sculptures independent of them, such as St. Matthew and the Angel of St. John by Gelsi in Campobasso or the analogous subject of S. Maria de Grazie in Frosolone. Works united by the same type of face, the folds of the coat, the dress and the position of the figure. Among the statues sculpted for the Parish Church of Campochiaro, St. Joseph appears closest to the Neapolitan Baroque lesson, interpreted by di Zinno in a popular and humble key.
