Resumen: Visits by Roman emperors provided provincials with exceptional opportunities to present their pleas. Epigraphic evidence from the high imperial period and particularly the 3rd century CE sheds light on this process of petition and response. The aim of the present paper is to study these inscriptions in order to understand the application and reception of Roman justice in the eastern provinces of the empire. Particular attention is devoted to noteworthy testimonies, such as the bilingual minutes from Dmeir (Syria), the petition of Skaptopara in Thrace, and related texts from Lydia. The essay will argue that the presence and legally binding decisions of emperors such as Diocletian could transform the perception of Roman rule among local populations, including the Jews.
