To Marcus Claudius Serenus, neokoros of the great Sarapis, one of the former chiliarchs, formerly prefect of the First Cohort of Damascenes, and chief cultivator, priest, exegetes, and to the Caesarea and the other prytaneis,
from Ammonios son of Theon son of Sarapion, of the Propappo-Sebasteian tribe and Althaean deme, one of those who became ephebes in the fifth year of Domitian. Wishing to enrol among the ephebes of the coming eighteenth year of Imperator Caesar Trajan Hadrian Augustus my son Nilammon, born to me by my sister Thaubarion, a citizen, who has died, I ask you to instruct those in charge of this matter, after receiving my written declaration on oath that the foregoing statements are true, to write to those whom it concerns to deal with me as I carry out what is required for the enrolment and ephebate of my aforesaid son Nilammon, and to notify the kosmetes and the gymnasiarch in office to admit him among the ephebes, so that I may have received a kindness.
[Nilammon son of Ammonios], ephebe from the city of Oxyrhynchus […]
The ephebate was youth training and civic registration tied to the gymnasium, giving privileged status; the father married his own sister, a practice attested in Roman Egypt. The APIS record wrongly assigns the regnal years to Trajan; the text names Hadrian.
