Holtz says that "the Good Friday 3-hour darkness 'over all the land'" and the "the Good Friday earthquake" "in fact went unnoticed by every non-Christian writer." The non-Christian Roman Phlegon reported the exact hours of the darkness and reported the Good Friday earthquake as a historical fact. The darkness was a historical fact; only the explanation was in question. Julius Africanus pointed out that the crucifixion darkness could not be naturalistically explained as an eclipse because Passover was a full moon. Holtz also claims that "The identification of Thallus' eclipse with "this darkness" might just be in the mind of Julius Africanus." Such an assertion is unreasonable. Thallus was clearly referring specifically to the darkness surrounding Jesus Christ's crucifixion. Julius Africanus was highly skilled at textual criticism, and traveled widely. Julius Africanus was committed to the truth, considered reliable by subsequent historians, had the resources and information access needed to be a qualified historian, and demonstrated historiographical integrity.
