From Africanus concerning the events associated with the passion of the Saviour and the life-bringing Resurrection
In the third book of his Histories, Thallos dismisses this darkness as a solar eclipse.1 In my opinion, this is nonsense. For the Hebrews celebrate the Passover on Luna 14, and what happened to the Saviour occurred one day before the Passover.2 But an eclipse of the sun takes place when the moon passes under the sun. The only time when this can happen is in the interval between the first day of the new moon and the last day of the old moon, when they are in conjunction. How then could one believe an eclipse took place when the moon was almost in opposition to the sun? So be it. Let what had happened beguile the masses, and let this wonderful sign to the world be considered a solar eclipse through an optical (illusion).
