According to Beševliev's edition and the inventory of the National Archaeological Museum, the provenance of the inscription is unknown. It is however mentioned in a catalogue of the finds from the excavations of Oescus in 1905, preserved in the archive of Václav Dobruský, then director of the Museum and head of the excavations. The photographic archive of the Museum also gives the provenance as Oescus.
The name of the deceased woman indicates Roman citizenship, and the gentilicium Aurelia sets the date after AD 212, when all free subjects of the Roman Empire became Roman citizens through the so-called Constitutio Antoniniana. Her cognomen is of Latin origin, from the superlative "felicissima" ("happiest"); her birthplace was (the administrative territory of) the city of Nicaea in the province of Bithynia, Asia Minor. The husband is referred to with a single name (cognomen), but he was seemingly a Roman citizen as well, possibly also with the gentilicium Aurelius.
It is worth noting the use of the Greek language which was rather rare in the Roman colony of Ulpia Oescus. This could be connected with the origin of the deceased from Asia Minor.
