The history of astrometry, the branch of astronomy dealing with the positions of celestial objects, is a lengthy chronicle, having its origins in earliest records of astronomical observations, and extending to the high accuracy observations today.

Why should an astronomer write a commentary on the Bible? Because commentators are not astronomers, and therefore either pass over the astronomical allusions of Scripture in silence, or else annotate them in a way which leaves much to be desired.
