In connection with this scriptural doctrine of winds came a scriptural doctrine of earthquakes: they were believed to be caused by winds issuing from the earth, and this view was based upon the passage in the one hundred and thirty-fifth Psalm, "He bringeth the wind out of his treasuries."(210) (210) For D'Ailly, see his Concordia astronomicae veritatis cum theologia (Paris, 1483--in the Imago mundi--and Venice, 1490); also Eck's commentary on Aristotle's Meteorologica (Ausburg, 1519), lib.

Such were the main typical attempts during nearly fourteen centuries to build up under theological guidance and within scriptural limitations a sacred science of meteorology.

But these theories were mainly evolved in the effort to establish a basis and general theory of phenomena: it still remained to account for special manifestations, and here came a twofold development of theological thought.
On one hand, these phenomena were attributed to the Almighty, and, on the other, to Satan.
