4. Many cases are recorded in history of the light of the sun being obscured at midday so as to result in almost total darkness, when it was known not to be produced by an eclipse. And it is probable that these natural events furnish the basis in part for those wild legends we have brought to notice. Humboldt relates in his Cosmos, that, "in the year 358, before the earthquake of Numidia, the darkness was very dense for two or three hours." Another obscuration of the sun took place in the year 360, which lasted five or six hours, and was so dense that the stars were visible at midday. Another circumstance of this kind was witnessed on the nineteenth of May, 1730, which lasted eight hours. And so great was the darkness, that candles and lamps had to be lighted at midday to dine by. Similar events are chronicled for the years 1094, 1206, 1241, 1547, and 1730. And if any such solar obscurations occurred near the mortal exit of any of the Gods above named, of course they would be seized on as a part of their practical history wrought up into hyperbole, and interwoven in their narratives, to give eclat to the pageantry of their biographies--a fact which helps to solve the mystery. ORIGIN OF THE STORY OF THE APHANASIA AT THE CRUCIFIXION. There is but little ground to doubt but that the various stories of a similar character then current in different countries, as shown above, first suggested the thought to Christ's biographers of investing history with the incredible events reported as being connected with the crucifixion. The principal motive, however, seems to have grown out of a desire to fulfill a prophecy of the Jewish prophet Joel, as we may find many of the important miraculous events ingrafted into Christ's history were recorded by way of fulfilling some prophecy. "That the prophecy might be fulfilled" is the very language his evangelical biographers use. Joel's prediction runs thus: "And I will show wonders in the heavens, and in the earth, flood and fire, and pillars of smoke. The sun shall be turned into darkness, and the moon into blood, before the great and terrible day of the Lord come." (Joel ii. 30.) A little impartial investigation will satisfy any unprejudiced mind that this poetic rhapsody has not the most remote allusion to the closing events in the life of Christ, and was not intended to have.
