Celsus

c. 25 BCE–c. 50 CE · Rome

Aulus Cornelius Celsus was a Roman writer of the early first century CE, active under the emperor Tiberius. He composed a wide-ranging encyclopedia covering subjects such as agriculture, law, philosophy, and the art of war, but the only part to survive is "On Medicine," a clear and systematic account of ancient medical knowledge. Written in elegant Latin by an educated layman rather than a practicing physician, it is one of our most important sources for the medicine of the early Roman Empire.

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.
