Tatian

? · Rome

Tatian (c. 120–185 CE) was an Assyrian-born Christian apologist and one of the most significant pupils of Justin Martyr in Rome. He is best known for two works: the Oratio ad Graecos (Address to the Greeks), a polemical defence of Christianity against pagan philosophy, and the Diatessaron, a harmony of the four Gospels that became the standard Gospel text in Syriac-speaking churches for centuries. After Justin Martyr's martyrdom (c. 165 CE) Tatian remained in Rome for some years before departing east around 172 CE. He is associated with the Encratite movement — an ascetic school that rejected marriage, meat, and wine — which took root and spread from Mesopotamia.

What they did here

Tatian came to Rome, converted to Christianity, became a pupil of Justin Martyr (Irenaeus, Adv. Haer. 1.28), and opened a Christian school there; the Address to the Greeks was composed during this Roman period, though its exact date — before or after Justin's martyrdom c. 165 — is disputed. His pupil Rhodon attests continued activity in Rome after Justin's death.

Rome in this era

Governed by the Roman emperors from the Antonines through the Tetrarchy, Rome housed a bishop's see of growing prestige, was the scene of periodic persecutions, and saw theologians such as Justin Martyr debate and die for the faith in the second century.

About Rome

# Rome In the late eleventh and twelfth centuries, Rome lay within the Papal States, the territorial domain of the Catholic Church, though its temporal glory as an empire had long faded. The city sprawled across its famous hills along the Tiber River, a landscape of crumbling ancient monuments, medieval fortifications, and Romanesque churches that dominated the skyline. The Jewish community of Rome was among Europe's most ancient, tracing roots to the second century BCE, and it flourished in a precarious but resilient position under papal authority; while confined to restricted quarters and subject to discriminatory laws, Roman Jews maintained a sophisticated intellectual and commercial life, with Hebrew scholarship and biblical commentary flourishing despite—or perhaps because of—the community's isolation. The Jewish quarter itself, densely packed and vibrant, became a center of learning where skilled scribes copied manuscripts and rabbinical discussions drew on centuries of local tradition. What made Rome extraordinary for Torah study was not merely its learned scholars but the tangible presence of antiquity itself: the community lived amid the ruins of pagan temples and Roman law, giving their interpretations of Jewish law a unique resonance, as if they were rebuilding Jewish civilization in the very streets where Roman power had once reigned supreme.
