For A Traveler Going From Any Place

The Two Revolutions, I Mean The Annual Revolutions Of The Declination And Of The Centre Of The Earth, Are Not Completely Equal; That Is The Return Of The Declination To Its Original Value Is Slightly Ahead Of The Period Of The Centre. Hence It Necessarily Follows That The Equinoxes And Solstices Seem To Anticipate Their Timing, Not Because The Sphere Of The Fixed Stars Moves To The East, But Rather The Equatorial Circle Moves To The West, Being At An Angle To The Plane Of The Ecliptic In Proportion To The Declination Of The Axis Of The Terrestrial Globe.

Pouring Forth Its Seas Everywhere, Then, The Ocean Envelops The Earth And Fills Its Deeper Chasms.

In The First Book I Shall Describe All The Positions Of The Spheres, Along With The Motions Which I Attribute To The Earth, So That The Book Will Contain As It Were The General Structure Of The Universe. In The Remaining Books I Relate The Motions Of The Remaining Stars, And All The Spheres, To The Mobility Of The Earth, So That It Can Be Thence Established How Far The Motions And Appearances Of The Remaining Stars And Spheres Can Be Saved, If They Are Referred To The Motions Of The Earth.
