The great popularity that the Tetrabiblos did possess might be attributed to its nature as an exposition of the art of astrology, and as a compendium of astrological lore, rather than as a manual. Ptolemy pursues tenaciously his novel objective of integrating closely the project’s theoretical and empirical phases and shows astonishing mastery of the concept, the design and the conduct of controlled experimental tests.

Ptolemy presented a useful tool for astronomical calculations in his Handy Tableswhich tabulated all the data needed to compute the positions of the Sun, Moon and planets, the rising and setting of the stars, and eclipses of the Sun and Moon. The treatise begins with Ptolemy’s study of pitches and intervals, for which he extracts both an idealized musical scale and a new acoustical tool.

Ptolemy’s comprehensive treatises on astronomy and geography were influential for nearly two millennia. He also divided illusions into those caused by physical or optical factors and those caused by judgmental factors.

That it did not haromnics attain the unrivaled status of the Almagest was, perhaps, because it did not harmojics some popular areas of the subject, particularly electional astrology interpreting astrological charts for a particular moment to determine the outcome of a course of action to be initiated at that timeand medical astrologywhich were later adoptions.

Ptolemy combined the mathematical, philosophical and physiological traditions. From inside the book.
