The Carmen Arvale and Rome's Oldest Surviving Religious Text

The Carmen Arvale, a hymn preserved by the Arval Brothers, an ancient Roman priestly college devoted to agricultural fertility rites, survives in a third-century CE inscription but preserves language and grammatical forms scholars consider substantially older, possibly archaic, reflecting the conservative nature of inherited ritual formulas that Roman religious practice, like many ancient traditions, treated as requiring exact verbal repetition rather than modernization for continued ritual efficacy. This pattern, in which religious Latin preserved older grammatical forms long after the spoken vernacular had changed, parallels the archaizing tendency found in other ancient liturgical languages, including Vedic Sanskrit and the archaic formulas within early Roman legal and augural practice, such as the specific wording required for valid auspices and treaties under Roman religious law.

Archaic Latin religious vocabulary and formulaic prayer structures influenced later Classical Latin religious and legal Latin considerably, and Roman priesthoods including the pontifices maintained specialized knowledge of correct archaic ritual language as part of their institutional religious authority within the Roman state religion.
