Ptolemy's Almagest is one of the most influential scientific works in history. A masterpiece of technical exposition, it was the basic textbook of astronomy for more than a thousand years, and still is the main source for our knowledge of ancient astronomy. This translation, based on the standard Greek text of Heiberg, makes the work accessible to English readers in an intelligible and reliable form. It contains numerous corrections derived from medieval Arabic translations and extensive footnotes that take account of the great progress in understanding the work made in this century, due to the discovery of Babylonian records and other researches. It is designed to stand by itself as an interpretation of the original, but it will also be useful as an aid to reading the Greek text.

On the lookout for a mind-blowing new perspective on the nature of God and humanity's place in the world today? Dive into The Marriage of Heaven and Earth, and enter the mind of a veritable rock star of contemporary theology-N. T. Wright. Marlin Watling takes abstract and complex ideas and grounds them in simple terms through his unique combination of readable summaries and fifty accompanying illustrations. He distills a lifetime of complex theological analysis and data into easy-to-consume sketches with explanations to provide one thing: universal access to a brilliant mind. Watling's guide comprises four parts � An introduction to N. T. Wright � Summaries of Wright's four key concepts � Wright's proposal of a new worldview � An overview of humanity's mission, with an eye toward the end times Following in the footsteps of reformer Martin Luther, N. T. Wright makes the old story new again with his paradigm-shifting worldview. And in The Marriage of Heaven and Earth, Watling does something equally novel. He enters the ivory tower, strips away the pomp and ceremony of untouchable academia, and presents to believers of all interest levels Wright's theology as it's truly meant to be: easy to understand and full of grace.
