What is Old Saint Peter's Basilica?

Old Saint Peter's Basilica was the original Constantinian basilica in Rome, built over Saint Peter's tomb from the 4th century until its demolition in the 16th century, central to studies of early Christian architecture, liturgy, and patronage.

Archaeological and textual analyses reconstruct its spatial layout, decorative programs, and ritual roles during Rome's Christianization. Over 100 papers explore its evolution from Constantine's foundation through medieval transformations (McEvoy 2010, 112 citations; Chenault 2008, 63 citations). Key sources include the Liber pontificalis and surviving drawings like those of Santa Croce (Mackie 2020, 28 citations).

Key Challenges

Why It Matters

Old Saint Peter's exemplifies sacred space transformation in late antique Rome, influencing Christian topography amid imperial decline (Chenault 2008). Senatorial patronage funded basilica expansions, linking aristocracy to papal authority (Behrwald 2016, 45 citations). Construction techniques shifted post-650 CE, marking medieval transitions visible in bonded-masonry analyses (Dey 2019, 43 citations). Liturgical texts like Ordo Romanus XI reveal baptismal rituals tied to its functions (Romano 2019, 28 citations).

Key Research Challenges

Fragmentary Archaeological Evidence

Demolition in the 16th century left limited physical remains, relying on drawings and excavations (Mackie 2020). Reconstructing layouts demands integrating sparse data from Santa Croce oratories. Modern digs beneath related sites like San Marco provide indirect analogs (Ammerman et al. 2017).

Interpreting Textual Sources

Liber pontificalis entries require critical editing to distinguish fact from hagiography (Franklin 2017, 29 citations). Jerome's accounts offer conflicted late antique views but demand contextual verification (Grig 2012, 35 citations). Senatorial donation records blend politics and piety (Behrwald 2016).

Patronage Network Tracing

Linking popes, senators, and emperors involves cross-referencing imperial visits and building phases (McEvoy 2010). Eighth-century technique shifts reflect Byzantine influences amid papal revival (Dey 2019). Heresy debates shaped fifth-century interventions (Cohen 2014).
