Cassius Dio
The similarities are noteworthy, for both Suetonius and Cassius Dio deal with Jews, tumult, Claudius, the city and expulsion, and Cassius Dio does provide a chronological context that points to the year AD 41. However, Cassius Dio does not mention Chrestus or any cause for the emperor's actions. Moreover, Cassius Dio says that Claudius "did not" drive the Jews out of the city, which prompts Slingerland to conclude that "Suetonius Claudius 25.4 does not refer to the event narrated in Dio 60.6.6-7." Rainer Riesner states that ancient historians generally hold that Cassius Dio here may have referred to an earlier, more limited action against some Jews, which was later expanded by Claudius to the expulsion of a larger group of Jews.
