Phlegon - refers to darkness at the time of Jesus' death

Phlegon, born about A.D. 80[1], was a secular historian who lived in the second century. There are two books credited to his name: Chronicles and the Olympiads. Little is known about Phlegon but he made reference to Christ. The first two quotes below are unique to Origen. The third quote is recorded by Philopon. The last quote is from Julius Africanus.

In the fourth year, however, of Olympiad 202, an eclipse of the sun happened, greater and more excellent than any that had happened before it; at the sixth hour, day turned into dark night, so that the stars were seen in the sky, and an earthquake in Bithynia toppled many buildings of the city of Nicaea." - Phlegon's 13th book quoted in Jerome's translation of Eusebius' Chronicle, 202 Olympiad

And with regard to the eclipse in the time of Tiberius Caesar, in whose reign Jesus appears to have been crucified, and the great earthquakes which then took place . . . ” - Origen, "Against Celsus", Book 2.33

Phlegon mentioned the eclipse which took place during the crucifixion of the Lord Jesus and no other (eclipse); it is clear that he did not know from his sources about any (similar) eclipse in previous times . . . and this is shown by the historical account of Tiberius Caesar. - Phiopon, De. opif. mund. II21

Phlegon records that, in the time of Tiberius Cæsar, at full moon, there was a full eclipse of the sun from the sixth hour to the ninth—manifestly that one of which we speak. But what has an eclipse in common with an earthquake, the rending rocks, and the resurrection of the dead, and so great a perturbation throughout the universe? . . . And calculation makes out that the period of 70 weeks, as noted in Daniel, is completed at this time. - Julius Africanus, Chronography, 18.1
