Imperial Decrees, Animal Sacrifices, and Christian Persecution

On 17 June 250 CE, Aurelius Sakis had a certificate drawn up that proved he and his children Aion and Heras had participated in the sacrifice of an animal to pagan gods. Two other men, Aurelius Serenus and Aurelius Hermas witness the declaration, confirming that they had actually witnessed the sacrifice.

“To those appointed to oversee the sacrifices, from Aurelius Sakis from the village of Theoxenis, with his children Aion and Heras, staying in the village Theadelphia. We have always sacrificed to the gods and now, too, in your presence, in accordance with the decree we have sacrificed and we have poured a libation and we have eaten of the sacrificial offering, and we ask you to undersign. May you continue to prosper.

We, Aurelius Serenus and Aurelius Hermas, saw you sacrificing.

The Year 1 of the Emperor Caesar Gaius Messius Quintus Traianus Decius Pius Felix Augustus, Pauni 23.” (P.Mich. III 157; translation by A. D. Lee)

Over forty such certificates written in the same year survive from Egypt and provide the only contemporary evidence of the edict ordered by emperor Decius (249–251 CE) that everybody in the Roman Empire was to perform a sacrifice to the Roman gods and the well-being of the emperor. Why would the emperor introduce such a policy? On one hand, the sacrifices were proof of loyalty to Decius, but they also were the first example of legislation that persecuted against Christians, as whoever refused to sacrifice would be punished. This leads to the question of who had to demonstrate that they were sacrificing: everybody, or just those accused of being a Christian? We don’t have enough information to answer this particular question.

The majority of the known Decian libelli (a word used to refer to short documents, especially official ones) come from the Fayumic town Theadelphia (modern Batn el-Harit), located 30 km northwest of Medinet al-Fayum. Smaller numbers, however, do survive from other sites, including Narmouthis and Oxyrhynchus – for the locations of all known libelli, see the table at the end of this post. P.Oxy. IV 658 is an example from Oxyrhynchus. Most of the man’s name is lost, but his children’s names survive, his son Dioscorus and his daughter Lais. The witness statements from this text are also now lost – only the smallest of traces survive of them.

“To the commissioners in charge of the sacred victims and sacrifices of the city. From Aurelius L[…]thion son of Theodorus and his mother Pantonymis, of the same city. Always have I continued sacrificing and pouring libations to the gods, and now in your presence in accordance with what has been ordered I have poured a libation and I have sacrificed and I have tasted of the sacrifices, together with my son, Aurelius Dioscorus, and my daughter Aurelia Lais. I request you to certify this for me below.

The year one of the Emperor Caesar Gaius Messius Quintus Traianus Decius Pius Felix Augustus, Pauni 20.” (P.Oxy. IV 658; translation from Blumell & Wayment)

This certificate shares many of the same features as the text from Theadelphia. Note that gods generally are mentioned – there is no specificity regarding to which gods sacrifices should be made. Imperial officials recording these sacrifices probably weren’t concerned about the identity of the gods, which almost certainly changed from place-to-place across the empire, only that the sacrifices took place.

The similarities between the texts indicate that the process of monitoring and recording the sacrifices was highly organised. The two examples given here are also very close in date – the Oxyrhynchus text was written only three days before the one from Theadelphia. In fact, nearly all of the known libelli date to June 250, approximately six months after Decius issued his decree. This six-month gap may suggest that the decree was not immediately adhered to, and so increased monitoring of sacrifices took place to ensure the emperor’s command was being carried out. However, it may simply be a case that communication of the order took this long to reach Egypt. Whatever the reason, these documents mark the beginning of a period of persecution of Christians across the empire, before the adoption of Christianity as its official religion in the fourth century.


*Note that the designation ‘Aurelius’ (‘Aurelia’ for a woman) marked somebody as a citizen of the Roman empire. Following the Edict of Caracalla (or Antonine Constitution) of 212, all free men in the empire were granted full Roman citizenship.
