All three Synoptic Gospels record the episode of Jesus casting a legion of demons into a herd of swine (Matt. 8:28-34; Mark 5:1-20; Luke 8:26-39). Only Mark gives the herd’s approximate number: “about 2,000.” Why were there so many pigs in this one location, and what’s the relevance?
Geographical-Sociocultural Setting
Jesus and his disciples were on the eastern coast of the Sea of Galilee in the mid-western Decapolis region near the village of Gergesa: predominately Gentile territory.1 Since the fourth-century-BC conquests of Alexander the Great, the cities of the Decapolis (mainly east of the Jordan) were Greek municipalities that were under Roman control from the first century BC. According to Jewish law, pigs were unclean animals and forbidden as a food source (Lev. 11:7-8; Deut. 14:8), but not among the Greco-Roman population.
Roman Dietary Preferences
Pork was one of the most popular meats in Rome.2 The Roman orator Callistratus considered pork to be “the most lawful flesh” (Plutarch, Quaestiones Conviviales 4.5.1). Emperor Caligula found it curious that the Jews did not eat pork and challenged a delegation from Philo to explain why (Philo, Legatio 45.361-62). Juvenal mocked the Jews of Judea for abstaining from pork and for allowing pigs to live to old age (Satire 6.160). Tacitus noted as unusual, “they abstain from swine’s flesh” (Hist. 5.4.2).
The Legio X Fretensis
Roman legions had been stationed in Syria since its establishment as a Roman province in 64 BC, the center of military operations overseeing the entire region, including the Jewish territories of Galilee and Judea. Around 41-40 BC the Legio X Fretensis (“Tenth Legion of the Strait”) was formed by Julius Caesar’s adopted son Octavian, defeating Marc Antony’s forces at the Battle of Actium in 31 BC that led to the founding of the Roman Empire and Octavian’s accession as Emperor Augustus Caesar. The legion was then stationed in Syria by at least AD 6, having engaged in repressing multiple Jewish uprisings and participating in the campaign to Judea led by legate Publius Sulpicius Quirinius (cf. Acts 5:37; Josephus, Ant. 18.1.1; 2.1).3 Documented in Syria in AD 18 (Tacitus, Annals 2.57.2),4 they were later involved in the Jewish-Roman War of AD 66-70 and contributed to the defeat of Galilean and Judean cities and the siege and destruction of Jerusalem.
The symbols of Legio X Fretensis were the goddess Venus (Octavian’s mythical ancestress), the bull (perhaps representing Taurus to symbolize the legion’s start around April-May), Neptune (god of the sea), a battleship (signifying victories at sea), and a boar (pictured above). This last symbol is pertinent to our study, seeing that pork was their preferred food.5
The Relevance of Mark’s Reference
To feed Roman legions and perhaps countless other pork-consumers who had settled in the general region, a sizeable number of pigs would have been necessary. Moreover, the Greeks regarded pigs to be among the more cost-efficient sacrifices in their cultic rituals, particularly during the annual Thesmophoria festival honoring Demeter (goddess of agriculture/ Roman Ceres) and her daughter Persephone (goddess of spring and queen of the underworld/ Roman Proserpina).6
Mark’s seemingly obscure attention to detail makes sense when viewed in its geocultural context. A herd of about 2,000 pigs is not only normal and expected but was probably just a meager fraction of what would have been needed and available for the local economy.
Conclusion
The Roman flavoring of Mark’s Gospel is highlighted by its heavy use of Latinisms,7 including the term “legion,” from the Latin legio, descriptive of a division of the Roman army of approx. 3,000–6,000 soldiers. In Mark’s telling of the story of Jesus, there appears to be a subtle anti-Roman sentiment: a “legion” of demons cast into a herd of pigs—the tenth legion’s symbol and favored food source—drowned in the sea. Despite Rome’s apparent dominance, the Son of God has arrived, he is more powerful, and his way is far superior.
