MATHEMATICIANS (MATHEMATICALS)
Prior to the advent of modern astrology tables and, especially, the computer revolution,
extensive mathematical calculations characterized the practice of astrology. For this
reason, the ancients often referred to astrologers as mathematicians or mathematicals.
MATHESIS
Mathesis, asteroid 454 (the 454th asteroid to be discovered, on March 28, 1900), is
approximately 88 kilometers in diameter and has an orbital period of 4.3 years. Its
name represents the desire for learning and the power of knowledge. In a natal chart,
Mathesis’s location by sign and house indicates where and how the desire for learning
is most likely to manifest. When afflicted by inharmonious aspects, Mathesis may
show aversion to learning or attraction to unhelpful subjects of learning. If prominent
in a chart (e.g., conjunct the Sun or the ascendant), it may indicate an exceptionally
studious person, or an individual for whom learning is a major life theme.

MATRIX ASTROLOGICAL SOFTWARE
Computers were made for astrology, although it took some astrologers a little time to
recognize this. Matrix Software, the first company to create computer programs and
make them available to the general public, was founded by astrologer Michael
Erlewine in 1977 in Ann Arbor, Michigan.
Prior to Matrix, astrologers did their charts using complex log tables, interpolation
techniques, and a pencil and paper or, at best, a four-function calculator. Some
astrologers even tried to make the argument that the age-old ritual look-up tables had
some special meaning in themselves and that computers had no soul. This retro attitude
did not last long and astrologers quickly came to love their computers.
Erlewine began programming on handheld-programmable calculators in the
early 1970s, in an attempt to research techniques for which there were no tables, such
