Ivy Goldstein-Jacobson (1893–1990) practiced in California, writing a
number of books. She adapted some classical methods, adding the use of
the word “cautions” for the considerations against judgment, and was
adamant that the horary had to be calculated for the location of the
querent, not the horary astrologer. She was inadvertently the originator
of the idea that planets in mutual reception “swap” or “exchange”
places. She also popularized the use of the parallel and added decanates
to horary delineation.
Barbara Watters (1907–1984) allowed the quincunx as an aspect,
brought back the use of eclipses in horary delineation, and used the
word “strictures” for the considerations against judgment (thereby
allowing later horary astrologers to refer to the “cautions and strictures”
and to attempt to distinguish between them).
Olivia Barclay (1919–2001) was largely responsible for the current
popularity of William Lilly and the revival of classical methods in
horary astrology. Originally trained in Goldstein-Jacobson’s methods,
Barclay switched when she accidentally found a partial original copy of
Lilly in a used-book shop.—J. Lee Lehman, Ph.D.Sources:
