The paper examines a painting representing the 'Martyrdom of Saint Giulia' by Paolo De Matteis. The work is presently preserved in the church of San Donato at Ripacandida, although it came from the nearby church of Santa Maria del Carmine. The work was painted around 1718, confirmed by the discovery of new archival documents, and was commissioned by Giuseppe Teroni to commemorate his wife who died on 11 August 1716.
The present paper emerges in the wake of various archive studies that have proved to be highly interesting from various points of view. The studies were carried out at Ripacandida (Potenza), in the church of San Donato (bishop of Arezzo and martyr). An examination of the documents has made it possible to reconstruct the origin of the 'Martyrdom of Saint Julia' painted by Paolo De Matteis. The canvas, conserved in Basilicata, thus represents a missing piece that further enriches the already substantial body of works by the Campanian painter.
