The article presents the epigraphic databases developed by the Ausonius Institute, highlighting the importance of integrating epigraphy with digital humanities. The flagship project, PETRAE , initiated in the 1980s, combines several Latin, Greek, and Gallic epigraphic corpora encoded in EpiDoc, based on comprehensive and detailed records. Its latest evolution, PETRAE 3.0, includes an interactive web interface and 3D visualization to facilitate the study of inscriptions. Other notable projects, such as ADOPIA , which specializes in the onomastics of the Roman Iberian Peninsula, and PATRIMONIVM , dedicated to Roman imperial properties, demonstrate Ausonius’ dynamism in applying digital technologies to ancient history. The future convergence of these databases into a common platform will optimize digital scholarly editing and facilitate collaborative research.
