About Marius
The Roman Martyrology commemorates Marius with Martha, Audifax, and Abachus on January 19. The Italian Episcopal Conference’s current entry calls all four martyrs and places their burial at the cemetery ad Nymphas on the Via Cornelia, thirteen miles from Rome. This brief liturgical notice confirms the group’s received identity and the burial tradition. It does not provide a secure year of death or details of Marius’s life before the group’s commemoration.
More elaborate accounts come from the Passio of Marius, Martha, Audifax, and Abacuc. Laura Vangone’s 2022 critical-edition study describes the text’s transmission and literary form as a hagio-martyrial itinerarium. That description matters for how its narrative should be used: travel, family ties, encounters, and scenes of persecution are details in a religious story passed down through manuscripts, not all independently verified facts. The Vatican State’s overview likewise emphasizes that the information is scarce and fragmentary and derives mainly from this late-antique Passio, later reworked for edifying purposes.
The traditional narrative presents Marius and Martha as a married couple and Audifax and Abachus as their sons. The Vatican State source notes that modern scholarship does not exclude the possibility that these were instead Christians linked in another way. Since the available evidence does not resolve the relationship, this profile does not encode Marius as a husband or father and does not create relationship rows. The account also associates the group with care for persecuted Christians and burial of martyrs, but these acts are not treated here as established events in Marius’s individual life.
The precise date of martyrdom is uncertain. The Vatican State overview says that accounts have varied, while current discussion tends toward an early fourth-century setting and the Diocletianic persecutions. The CEI calendar entry supplies no death year, so the catalog leaves life dates blank. Its cemetery notice is a burial tradition, not a precise place of execution; no individual death place or event is inferred from it.
The Roman Catholic calendar commemorates Marius with the other three on January 19. This observance belongs to the group and should not be mistaken for an independently established date of death. The profile remains focused on what current calendar and critical sources support: Marius is one of a four-person martyr group remembered at Rome, whose detailed account survives chiefly through a critically studied Passion. He is not the similarly named Marinus/Amarinus associated with Praejectus of Clermont.
