The application of FAIR (Findable, Accessible, Interoperable, Reusable) principles can revolutionise the epigraphic discipline by facilitating quantitative and reproducible research. Despite the richness of Latin inscriptions, the lack of low-barrier tools for accessing and analysing these datasets has hindered large-scale studies and the uptake of FAIR and Open Science principles in ancient studies. The LatEpig v2.0 tool addresses this gap by enabling researchers to programmatically access the Epigraphic Database Clauss-Slaby, and generate reproducible research following state-of-the-art standards. The main aim of LatEpig is to democratise data access and enhance research potential without requiring advanced technical skills. A case study on ‘viator’ inscriptions exemplifies the tool's utility, illustrating spatial and temporal trends in inscriptions addressing messengers and travellers across the Roman Empire. LatEpig exemplifies that the development of similar tools is crucial for advancing FAIR and Open Science practices in the Humanities, ensuring that substantial investments in digital resources are fully realised.
