In a second account, the place of their martyrdom was appellatur Coloniacum, qui dicitur Colonia ("called Coloniacum, that is to say, Colonia"), which may be Colonia Iulia Castrumnovurn. Their bodies were collected by a man named Deodatus and buried in that place. According to a third account, their cult was localized in the basilica of San Pietro in Tuscania. The Acts of Felinus and Gratian were based on those of Secundian and his companions. Sabine Baring-Gould writes that "the so-called Acts of SS. Gratian and Felinus, used as lections in the Arona Passionale, are extracted from the Acts of SS. Florentinus and Companions, martyrs at Perugia commemorated the same day. But these Acts are in their turn not genuine; they are, in fact, the Acts of SS. Secundianus and Comp. (August 9)."
