Throughout the Mediterranean the study of the destruction, reuse, moving and preservation of statues has provided a window onto the transformation of Rome during a time of ascendant Christianity. The preservation of statuary collections is increasingly important in this regard. Archival research has revealed the discovery of one such collection at Ostia's Sanctuary of Magna Mater, a treasure trove of sculptures, reliefs and at least one bronze statue. All were well preserved, and several were found in the open spaces of the sanctuary. Together they span 500 years of history, stretching into the late fourth century. Unfortunately, the late antique significance of this group has never been acknowledged. This paper situates that collection within the social world of late antique Ostia, where many statues of both sacred and non-sacred subjects remained on display. The late fourth-century dedication, in particular, set alongside the earlier pieces, demonstrates that the ‘mood and motivations’ of traditional Roman religion, in Clifford Geertz's terms, also remained quite visible. The presence of this accumulated tradition, a hallmark of Rome's ‘civil religion’ for centuries, testifies to the high social status afforded one of Ostia's most historic sites, even during an increasingly Christian age.
