The grammar of astrology : containing all things necessary for calculating a nativity by common arithmetic / by Zadkiel the seer.
The Grammar of Astrology, written by Richard James Morrison under the pseudonym Zadkiel the Seer and published in London in 1833, is a practical manual for astrologers on calculating a birth chart by ordinary arithmetic. Its pictures are circular diagrams with radiating house lines, zodiac signs, and planetary glyphs, showing the layout a designer could borrow for radial or astrological graphics.
