The monograph of Alexander Weiß on public slavery in the cities of the Roman Empire based on Greek and Latin inscriptions shed light on the role and functions of the public slaves, arguing that they had a much larger role in the administration of the provincial cities than previously thought. Weiß intended to collect all epigraphical data on public slavery, although he could not study some smaller corpora in Pannonia, like IlJug or the Corpus of Greek inscriptions found in Pannonia (CIGP). A new collection of inscriptions from Aquincum (Tituli Aquincenses) and new inscriptions offer a great opportunity to reexamine the epigraphical data of Pannonia on public slavery, and examine whether the public slaves of Pannonia fit into the administrative categories listed by Weiß, or might reveal new functions.
