The first great conflict was in reference to geography--the shape and surface of the earth. When science disclosed the fact that the earth was round, there was a great commotion, and so much the more since it was by Mahometan scholars that the discovery had been made. It was asked, "Can any good thing come out of Nazareth?" In other words, "Is it possible for vile Mahometans to understand and teach such a truth when it is not yet known to the assumed church of God?" At {27} once the war-spirit became fierce and hot. The great writer Eusebius treated the doctrine with contempt. Lactantius asks, "Is there any one so senseless, as to believe that there are men whose footsteps are higher than their heads? That the crops and trees grow downwards? That the rains, snow and hail fall upward to the earth?" (_For further particulars see Whewel's Hist. Induct. Sciences, Vol. I, page_ 196.) At this stage of the controversy, Cosmas Indicopleustes, by direction of the Catholic church, undertook to give a description of the earth. According to Cosmas, the universe is in the form of an immense box, twice as broad as it is high and twice as long as it is broad. At the bottom of this box lies the earth, surrounded by four great seas or oceans. At the outer edges of these seas, rise immense walls, which support the vault of heaven, even as the walls of a house support the roof; and thus walls and vault shut in the earth and all the heavenly bodies. This vast box he divides into two compartments or stories. In the lower one men were said to live, and sun, moon and stars to move. The upper one was said to be the abode of God and angels, whose principal work was to push and pull the sun and planets to and fro, and to open the windows of heaven, and thus regulate the quantity of rain. The ignorance or impudence of Cosmas can only be partially imagined, when we recollect that he supported his theory by reference to the Bible, and quoted _Genesis i_, 6; _Job xxvi_, 11; _Psalms cxlviii_, 4; _Isaiah xl_, 22. All the sublime poetry and {28} beautiful imagery of these texts were thus debased to give credence to the wild vagaries of this ignorant man.
