Questions that the priest could not answer he declared were forbidden of man to know; and when men attempted to find out for themselves they were looked upon as heretics.
The early church regarded the earth as a flat surface with four corners. And in proof of their position they quoted Saint Paul, who wanted the gospel carried to the ends of the earth.
In fact, the universe was a house. The upper story was Heaven, the lower story was the Earth, and the cellar was Hell. God, the angels and the "saved" lived in Heaven, man lived on Earth, and the devils and the damned had Hell to themselves.
"And there shall be no night there," and this was proven by the stars, which were regarded as peepholes through which mortals could catch glimpses of the wondrous light of Heaven beyond. Hell was below, as was clearly shown by volcanoes, when the fierce fires occasionally forced themselves up through. Darkness to children is always terrible, and the night is regarded by them as the time of evil.
Later, Churchmen came to believe that the stars were jewels hung in the sky every night by angels whose business it was to look after them.
The word "firmament" means a solid dome or roof. This firmament, the sky, was supposed to be the floor of Heaven. The firmament had four corners and rested on the mountains, as the eye could plainly see. When God's car was rolled across the floor we heard thunder, and his movements were always accompanied by lightnings, winds, black clouds and rain—all this so He could not be too plainly seen.
Heaven was only a little way off—a few miles at the most. So there were attempts made at times by bad men to reach it. The Greeks had a story about the Aloidæ who piled mountain upon mountain; the Bible story of the Tower of Babel is the same, where the masons called, "More mort," and those below sent up bricks. There is also an ancient Mexican legend of giants who built the Pyramid of Cholula, and they would have been successful in their attempts if fire had not been thrown down upon them from Heaven. In all "Holy Writ" we find accounts of "ascensions," "translations," "annunciations," and mortals caught up into the clouds. Many people had actually seen angels ascending and descending.
"Messengers from on high" and God's secretaries were constantly coming down on delicate errands. Everything that man did was noted and written down. We were watched all the time by unseen beings. The Bible tells of how the Earth was eventually to be destroyed, and then there would be only Heaven and Hell. God, His Son and the angels were going to come down, and for ages men watched the heavens to see them appear.
All sensitive children, born of orthodox Christian parents, who heard the Bible read aloud, looked fearfully into the sky for "signs and wonders." The Bible tells in several places of devils breaking out of Hell and roaming over the earth. Dante fully believed in this three-story-house idea, and pictures with awful exactness the details, which he gained from the preaching of the priests. Dante was never honored by having his books placed on the "Index." On the contrary, he got his vogue largely through the recommendation of the priests. To them he was a true scientist, for he corroborated their statements.
The Christian Fathers ridiculed the idea of the earth being round, because, if this were so, how could the people on the other side see the Son of Man when He came in the sky? Besides that, if the earth were round and turned on its axis, we would all fall off into space.
