Nicolay Sharankov dates the inscription according to the revised date of Eustochius Celer's office. He was a thracarch (president of the Thracian koinon) in AD 248-249, during the rule of Philippus Arabs and Otacilia Severa.
Eustochius Celer was a Roman citizen, but this inscription gives only his two cognomina - Eustochius (Greek) and Celer (Latin). His father was a Roman citizen as well but is mentioned here only by his Greek cognomen.
The dedicant's full name was Marcus Aurelius Eustochius Celer. His father Aurelius Asclepiades is attested as a legal representative of a religious society in AD 244-245 in an inscription from Cellae (IGBulg 1517) where the son is mentioned only with the name Celer. Eustochius Celer appears as thracarch in two other inscriptions (IGBulg 1537 and AE 2018, 1430) and without an office in IGBulg 5591.
