Astronomy is the most ancient of all sciences, and has been the introducer of vast knowledge; it was familiarly known to the Hebrews, for they diligently noted the course of the heavens, as God said to Abraham: “Behold the heavens; canst thou number the stars?” etc. . . . Astronomy deals with the matter, and with what is general, not with manner of form. God himself will be alone the Master and Creator, Lord and Governor, though he has ordained the stars for signs. 1
