The crucifixion darkness is an event described in the synoptic gospels in which the sky becomes dark in daytime during the crucifixion of Jesus for roughly three hours.[1][2][3] Most ancient and medieval Christian writers treated this as a miracle, and believed it to be one of the few episodes from the New Testament which were confirmed by non-Christian sources. Modern scholars have found references by early historians to accounts of this event outside the New Testament, although no copies of the referenced accounts survive.[4]
In his Apologeticus, Christian apologist Tertullian in AD 197 considered this not an eclipse but an omen, which is recorded in Roman archives. In his apologetic work Contra Celsum, the third-century Christian scholar Origen offered two natural explanations for the darkness: that it might have been the eclipse described by Phlegon of Tralles in his Chronicle or that it might have been clouds. In his Chronicle of Theophanes the fifth-century chronicler George Syncellus quotes the History of the World of Sextus Julius Africanus as stating that a world eclipse and an earthquake in Judea had been reported by the Greek 1st century historian Thallus in his Histories.
