Astronomy is said to be the oldest and noblest of the physical sciences. Thus, the fundamentals of astronomy, which were a matter of daily observation to early astrologers, became a lost art. Most astrological textbooks devote little or no space to this subject, which has long been looked upon as an occult art requiring years of study, a thorough knowledge of higher mathematics, and a deep understanding of fundamental science. Also included in this exceptional volume is an extensive section on the astrological ages, with historical dates and decans; information about eclipses; an explanation of modern and ancient calendars; and the evolution of the planisphere and house division.
