Not to be confused with the Saint Proietto said to have been martyred along with Saint Evasius at Sedula (the modern Casale Monferrato where the relics of both are preserved in the cathedral); nor with the Saint Proietto venerated in the area of Cavour (the ancient Caburrum) who has been traditionally linked with the Theban Legion, but is perhaps more likely to have been an early bishop of the town. (See Damiano Pomi (2004), "San Proietto", Santi, beati e testimoni.)
