On the façade, four giant pilasters with Corinthian capitals support an entablature and pediment.
Together these elements recall the front of ancient temples, such as the Pantheon in Rome. There is also a grand arch in the center of the façade that is supported, at least visually, by two shorter fluted pilasters. Taken together, the lower façade, with its tall central arch and flanking side doors evoke ancient triumphal arches such as the Arch of Constantine.
Ancient Rituals
The center arch extends deep into the facade itself, creating a recessed barrel vault that frames the main entrance to the church. The arch and its coffered barrel vault form a perfect setting for processions of the holy relic and the celebration of Christ’s triumph over death. Such spectacles would recall ancient processions where victorious warriors paraded through Rome's triumphal arches.
