Serapia

What it was

The Serapia, also spelled Sarapia, was a religious festival of the Roman Empire. Its god was Serapis, a figure the Greek world and Egypt shared, and the day was set aside as a rite for him and for Isis Pharia, the Isis of the Lighthouse at Alexandria. Farmers' almanacs, the menologia rustica, list the occasion in the first half of the first century. It was not a private devotion but a public date: the Calendar of Filocalus, drawn up in 354, still carries it as an official holiday.

From Alexandria to Rome

Serapis mattered in Alexandria, where he served as a city god, and that standing brought him into the Imperial cult of Rome. There he received grand titles: Dominus, or Master; Magnus, the Great; and Invictus, the Invincible. Worshippers treated him as a giver of success and victory, and set him beside Sol or Helios, Jupiter or Zeus, and Neptune. The festival therefore belonged to two worlds at once. In Egypt it kept its older shape; at Rome it joined the round of state religion, with the emperor's authority behind it.

How it was kept

The Egyptian Serapia was a public procession with paid entertainment. A papyrus from the late third century records what the organizers paid for at Oxyrhynchus: a comedian, two reciters known as Homerists, dancers and athletes. Among those taking part was a figure called the kynopou, the dog-headed one, probably a celebrant dressed as Anubis. This dog-headed performer received a fee from the festival and also welcome gifts, xenia, from people who watched along the route. Townspeople lined the way, and the procession moved through the streets with music, costume and sport.

Anubis and the afterlife

Among Greeks and Romans, Serapis could stand for Pluto, the ruler of the dead, and Anubis for Cerberus, the hound at the gate. That reading explains the welcome gifts handed to the dog-headed figure: by offering hospitality along the procession, a person hoped for hospitality in return after death. For Egyptians the meaning was different. Anubis at the head of the rites tied the Hellenistic Serapis back to Osiris, one of their oldest gods, and showed that the newer worship still stood on Egyptian ground.

On the calendar

Two kinds of record keep the Serapia's date. Farmers' almanacs from the first half of the first century mark it as a sacred day for Serapis and Isis Pharia. Three hundred years later, the Calendar of Filocalus of 354 still lists 25 April as a holiday. Papyri carry the Egyptian celebrations forward to 315. Together these sources show a date that outlasted changes of dynasty, religion and language, kept in the countryside and in the city, written down by officials and by farmers alike.

How Serapia is kept

The day was given to Serapis and to Isis of the Lighthouse. In Egypt it took the form of a procession through the streets, led by paid performers and by a costumed figure playing Anubis. Organizers hired the entertainers, and the man who took the part of the dog-headed god collected both his fee and gifts of welcome from onlookers. Athletes, dancers, a comedian and reciters took part. At Rome the observance sat within the state religion, where Serapis was honored under titles of mastery and victory alongside the sun, the sky and the sea.

When and where

It fell each year on 25 April. The date is fixed in the Roman calendar rather than tied to the moon or the harvest. Farmers' almanacs of the first century list it, the Calendar of Filocalus of 354 still records it, and papyri show Egyptian celebrations in 315.

Alexandria was its home, since Serapis was that city's god, and Rome took it up through the Imperial cult. Papyrus records place celebrations at Oxyrhynchus in Egypt. Because official calendars of the empire carry the date, it was probably observed in many provinces, but the surviving descriptions come from Egypt and from Roman state practice.

What Serapia means

Serapis stood for success and victory, and his titles spoke of mastery and power that could not be beaten. The procession carried a second, quieter meaning. Gifts offered to the dog-headed figure were a wager on the world after death: kindness shown on the street might be repaid beyond it. For Egyptians, Anubis walking with Serapis kept the old god Osiris in view, so the festival joined Greek and Egyptian hopes in one rite.
