A new and complete illustration of the celestial science of astrology : or, The art of foretelling future events and contingencies, by the aspects, positions, and influences of the heavenly bodies : founded on natural philosophy, scripture, reason, and the mathematics ... in four parts ...
Ebenezer Sibly's four-part astrology manual, printed in London in 1817 for students of horoscope casting and natural philosophy. The plates are square horary charts built from heavy black rules and quartered X marks, with houses labelled by compass angle and filled with planetary and zodiac glyphs in small type — usable as diagram frameworks, astrological symbol sets, and geometric ornament.
