In the aftermath of the Bar Kokhba revolt, the land lay broken. Jerusalem had been razed and rebuilt as the Roman city Aelia Capitolina. Jews were forbidden to enter it. And sometime around 135 CE - the precise sequence of Hadrian's edicts is still debated by scholars - the Emperor issued a decree that struck at something older and more intimate than any city: a ban on circumcision. To perform brit milah was to break Roman law. The penalty was severe enough to push the practice underground. The empire, which had swallowed a dozen peoples without notable effort, was reaching now into the homes and bodies of the Jewish people and commanding them to stop.
They did not stop. This is the thing that needs saying plainly before anything else. Hadrian's edict did not end the practice. It drove it underground. Families gathered in the dark, without the community ceremony, without the customary celebration, and made the cut on the eighth day as they always had. To understand what that meant requires imagining the weight of it: a mother and father who had themselves been circumcised or born into a circumcised household, who knew what the mark meant, who had lost brothers or cousins or neighbours in the revolt, who now had eight days to decide whether they would defy the most powerful state in the world - with their infant son's body as the ground of that defiance.
The record
The Historia Augusta - a late Roman collection of imperial biographies of uneven reliability, but drawing on earlier sources - records that Hadrian prohibited circumcision. The historian Sextus Aurelius Victor (De Caesaribus, 14.2, fourth century CE) also notes this prohibition. More significantly, rabbinic sources from the period register the ban directly. The Tosefta (Shabbat 15:9) and the Jerusalem Talmud (Yevamot 8:1) record rulings made under conditions of persecution (she'at ha-shmad, "the time of forced apostasy") in which rabbis debated how to weigh the risk of death against the obligation to circumcise. The Babylonian Talmud (Yevamot 72a-b) preserves a tradition that circumcision ceased during the wilderness wanderings and was restored by Joshua - but the Talmud's editors were working in a period that still remembered the Roman suppression, and the anxiety about interruption and restoration of the rite runs through the passage. The ban was real enough that it required legal reasoning to navigate.
The rabbis who survived the revolt - who were, by this point, already assembling what would become the Mishnah - faced a practical problem. Halakha is clear: the commandment to circumcise on the eighth day is one of the weightiest positive obligations in the Torah. It overrides the Sabbath. It overrides numerous other concerns. But does it override the preservation of life? The principle of pikuach nefesh - that saving a life supersedes almost all other commandments - sits in direct tension with the duty to circumcise when circumcision means death. The rabbinic discussions from this period do not resolve the tension by abandoning the rite. They resolve it by distinguishing between public and private risk, between immediate lethal threat and general legal prohibition, and by insisting that the commandment remains binding even when its fulfilment requires extraordinary courage. This is not theoretical hair-splitting. It is a community deciding, in real time, how to remain itself under conditions designed to prevent it.
The record
Hadrian's circumcision ban was eventually reversed or modified under his successor Antoninus Pius (r. 138-161 CE). The Historia Augusta (Life of Antoninus Pius, 5.2) records that Antoninus permitted Jews specifically to circumcise their own sons, while extending the prohibition to non-Jews - a legal distinction that acknowledged the rite's centrality to Jewish identity. This reversal is confirmed by the legal record: the Digest of Justinian (48.8.11), a sixth-century compilation drawing on classical Roman law, preserves a rescript attributed to the Antonine period that distinguishes Jewish circumcision from the broader prohibition. The survival of the practice into the period when it became licit again - the fact that there were Jewish boys being circumcised in 140 CE, 150 CE, 160 CE - is direct evidence that the ban had not succeeded. The communities that kept the covenant in the dark passed it back into the light. Antoninus did not restore a practice that had been extinguished; he decriminalised one that had never stopped.
The scholar Shaye J. D. Cohen, in his work on Jewish identity in the Greco-Roman world, observes that circumcision functioned in antiquity not merely as a religious rite but as the primary bodily marker of Jewish male identity - visible, permanent, and impossible to fake in either direction. In a world without identity documents, without surnames as we understand them, without institutional records of membership, the body was the proof. Hadrian's ban was an attack on that proof - an attempt to make the next generation ambiguous, to blur the boundary that the Jewish community had maintained for centuries. The families who circumcised their sons under the ban were preserving exactly that clarity: this child is one of us, the mark says so, and no emperor's edict changes what the mark means.
There is something almost unbearable in the image: a Roman province emptied of its population, a city renamed to erase even the memory of what it had been, a people forbidden to enter it - and still, in the back rooms and the hidden courtyards of the diaspora communities that survived, on the eighth day after each birth, a father holding his breath and the covenant holding. Hadrian is gone. The ban is gone. The circumcision is not.
