C. Helvidius Priscus arbiter ex compromisso

This article concerns the identity and role of the C. Helvidius Priscus who is named in CIL IX, 2827 as an arbiter ex compromisso in a boundary dispute. After examining the inscription itself, I proceed to examine the implications of the mechanism of arbiter ex compromisso in the Roman judicatory system, and the possibility of a high-ranking Roman serving in such a role. The seemingly discrepancy between a high-ranking Roman and the role of a land surveyor is resolved hereby by juxtaposing it twice: once with the precedent of high-ranking surveyors in the agrarian bill of Rullus; and secondly, by reading it in the context of locatio conductio operis contracts.
