The Bar Kokhba Revolt and Aelia Capitolina

Estimated date

The Jews of Judaea rise against Rome under Simon bar Kosiba, called Bar Kokhba. Hadrian’s armies crush the revolt at great cost, Jerusalem becomes the Roman colony Aelia Capitolina, and Jews are barred from the city.

Cassius Dio, whose account survives only in a later abridgement, says that the emperor Hadrian founded a city at Jerusalem in place of the one razed in the Jewish Revolt and the Destruction of the Temple, named it Aelia Capitolina, and raised a temple of Jupiter on the site of the temple. This, Dio says, brought on the war: the Jews could not bear to see foreigners settled and foreign rites planted in their city (Cassius Dio, Roman History 69.12). A late Roman biography of Hadrian gives another cause, a ban on circumcision (Historia Augusta, Hadrian 14.2).

By Dio’s account the rebels waited until Hadrian had left the region. They avoided open battle and fought from fortified positions and underground passages (Cassius Dio, Roman History 69.12). Eusebius, in the fourth century, calls their leader Barcocheba and says the name means “star” (Eusebius, Church History 4.6). Letters found in caves near the Dead Sea show that he was Simon bar Kosiba: they are his orders to his officers to send men and take over grain (Bar Kokhba letters) and, in one case, to bring palm branches and citrons, which its excavator, Yigael Yadin, connected with the feast of Sukkot (Bar Kokhba letters letter to Yehudah bar Menashe). A coin of his first year names “Shimon Prince of Israel” and is dated “Year 1 of the Redemption of Israel” (Coin of Bar Kokhba, year 1 (Harvard Art Museums 2008.2.105)).

Dio goes on: Hadrian sent his best generals, among them Julius Severus, brought from Britain. Severus avoided pitched battles, cut off small groups and starved them out. Dio counts fifty strongholds and 985 villages destroyed and 580,000 men killed in the fighting, and says that nearly all Judaea was left desolate. Roman losses were so heavy that Hadrian, writing to the senate, left out the customary words “I and the legions are in health” (Cassius Dio, Roman History 69.13–14). Eusebius says that the war was fiercest at Betar, a strong fortress not far from Jerusalem, where after a long siege the rebels were worn down by hunger and thirst and their leader “suffered his just punishment” (Eusebius, Church History 4.6). The Mishnah lists the capture of Betar among the disasters of the ninth of Av (Mishnah, Ta’anit 4:6).

Afterwards, Eusebius reports from Aristo of Pella, Jews were forbidden by Hadrian’s decree to enter the district of Jerusalem (Eusebius, Church History 4.6). Justin Martyr, writing some twenty years later, says that a Jew caught entering it faced death (Justin, First Apology 47). He also says that during the war Bar Kokhba ordered Christians to be cruelly punished unless they denied Jesus Christ (Justin, First Apology 31).

For the church of Jerusalem, as Eusebius tells it, the war was a break. He reports that its first fifteen bishops, down to this siege, are said to have all been of Hebrew descent, and that the Roman city which then arose, colonised by another people, had a church made up of Gentiles, with Marcus as the first bishop after those “of the circumcision” (Eusebius, Church History 4.5) (Eusebius, Church History 4.6).

How this is dated

Estimated date. A scholarly estimate from primary evidence, with a margin of years.

No ancient writer gives the years of the war. Cassius Dio says only that the Jews rose once Hadrian had left Egypt and Syria (Cassius Dio, Roman History 69.12). Eusebius, citing Aristo of Pella, puts the height of the fighting, at Betar, in Hadrian’s eighteenth year, which ran from August 134 to August 135 (Eusebius, Church History 4.6). The rebels dated their coins by an era of their own; a coin of “Year 1 of the Redemption of Israel” is assigned to 132–133 by the museum that holds it (Coin of Bar Kokhba, year 1 (Harvard Art Museums 2008.2.105)), and the Israel Antiquities Authority dates the documents from the refuge caves to 132–135 (Bar Kokhba letters). The beginning in 132 is generally accepted. The end is put late in 135 or early in 136.

The sources also disagree about the order of events. Dio makes the founding of Aelia Capitolina the cause of the war (Cassius Dio, Roman History 69.12); Eusebius describes the Roman city as arising after it (Eusebius, Church History 4.6). Werner Eck, “The Bar Kokhba Revolt: The Roman Point of View”, Journal of Roman Studies 89 (1999), pp. 76–89, sets out the evidence of Roman inscriptions for the scale of the war.
