Mark Allan Powell observes that there were only three significant Roman historians worthy of note in the first century.

The three most important Roman historians for the first-century period are Tacitus, Suetonius, and Josephus. All three mention Jesus, as do a couple of other Roman writers. Only Josephus, however, has much to say about him. In general, the Romans were much more interested in Christianity than in Jesus himself.
