The Giacomo Farelli is certainly a notable representative of Neapolitan painting in the second half of the seventeenth century, even if studies of his interesting and prolific career are still ongoing. The catalogue of his works has grown steadily over recent decades and shows that he was one of the protagonists on the Abruzzo stage, where he was especially active in working on commissions from the noble families as well as serving important political and administrative appointments. This article is about the discovery and attribution of a number of unpublished canvases in the churches of San Giovanni Apostolo in Sulmona and San Giovanni Battista in Atri, with an analysis of their patronage, iconography and stylistic relationships with other works also recently found in the region, such as the Madonna del Rosario in the church of San Domenico in Chieti or — in contrast — works lost some years ago, such as is the case of the lateral sections of the triptych in Sant’Eustachio in Cermignano.
