“Look at this ray of light which enters by my window,” said the abbé, “and then observe the lines traced on the wall. Well, by means of these lines, which are in accordance with the double motion of the earth, and the ellipse it describes round the sun, I am enabled to ascertain the precise hour with more minuteness than if I possessed a watch; for that might be broken or deranged in its movements, while the sun and earth never vary in their appointed paths.”

This last explanation was wholly lost upon Dantès, who had always imagined, from seeing the sun rise from behind the mountains and set in the Mediterranean, that it moved, and not the earth. A double movement of the globe he inhabited, and of which he could feel nothing, appeared to him perfectly impossible. Each word that fell from his companion’s lips seemed fraught with the mysteries of science, as worthy of digging out as the gold and diamonds in the mines of Guzerat and Golconda, which he could just recollect having visited during a voyage made in his earliest youth.

“Come,” said he to the abbé, “I am anxious to see your treasures.”
