John Keill Quote

There is nothing in Astronomy which shews the great Sagacity of Human Understanding, and its deep Penetration, more than a clear Explication of the Suddain Disappearings of the Sun and the Moon, that is, of their Eclipses; and the accurate Predictions when they are to come to pass, which the Astronomers can now foretell almost to a Minute.
