under it; when the sun passed behind this mountain it was night, and when it emerged from it, it was day. And certainly under the crystal box of the monk it would be in vain to attempt, by passing westwards, to arrive at the far east. The cosmogony of Cosmas was also that of the doctors of Salamanca; and the views of Columbus were denounced as heterodox because they failed to conform to it. Such was one of the earlier mistakes of the theologians. When merely told regarding the authorship of the chronometer, they held that they had been told also respecting the mechanism of the chronometer. Attaching literal meanings to what we now recognize as merely poetic or oratorical figures, they believed that not only was it revealed to them that God had created the heavens and earth, but also that he had created the earth in the form of an extended plain, and placed a semi-globular heavens over it, just as one places a semi-globular case of glass over a piece of flower-plot or a miniature thicket of fern. And how, I ask, was this error ultimately corrected? Simply by that science of the geographer which demonstrates that the earth is not flat, but spherical, and that the heavens have not edges, like a skin-tent or glass-case, to come anywhere in contact with it, but consist mainly of a diffused atmosphere, with illimitable space beyond. [Illustration: Fig. 115. THE HEAVENS AND EARTH OF COSMAS.[34] (_Sectional View._)] The second great error to which the theologians would fain have pledged the truth of Scripture was an error in the astronomical province. I need scarce refer to the often-adduced case of Galileo. The doctrine which the philosopher had to "abjure, curse, and detest," and which he was never again to teach, "because erroneous, heretical, and contrary to Scripture," was the doctrine of the earth's motion and the sun's stability. But to the part taken by our Protestant divines in the same controversy,--men still regarded as authorities in their own proper walk,--I must be allowed to refer, as less known, though not less instructive, than that enacted by the Romish Church in the case of Galileo. "This, we affirm, that is, that the earth rests, and the sun moves daily around it," said Voetius, a great Dutch divine of the middle of the seventeenth century, "with all divines, natural philosophers, Jews and Mohammedans, Greeks and Latins, excepting one or two of the ancients, and the modern followers of Copernicus." And we detect Heideggeri, a Swiss theologian, who flourished about half an age later, giving expression, a few years ere the commencement of the last century, to a similar view, as the one taken by himself and many others, and as a view "from which," he states, "our pious reverence for the Scriptures, the word of truth, will not allow us to depart." A still more remarkable instance occurs in Turrettine, whom we find in one of his writings arguing in the strictly logical form, "in opposition to certain
