Only after Theodosius did the processions become a religious event, replete with icons, crosses, and banners. There were other local processions connected with the primitive worship of the country people, which remained unchanged, but they were eventually overshadowed by the popular piety of the Church. Such were those of the Ambarvalia, Robigalia, which were essentially rustic festivals, lustrations of the fields, consisting in a procession round the spot to be purified, leading the sacrificial victims with prayers, hymns, and ceremonies to protect the young crops from evil influence.
