as-cen-sions
Phonetic: /əˈsɛn.ʃənz/
In Medieval astrology, ascensions are measurements related to the rising of zodiacal degrees or celestial bodies above the eastern horizon.
This concept was central to Medieval astronomy and astrological calculation. Ascensions were used to determine how signs and degrees rise according to geographic latitude, forming the basis for calculations involving house systems, primary directions, oblique ascensions, and right ascensions. Because signs do not rise uniformly outside the equator, Medieval astrologers relied on ascensional measurements to calculate planetary positions and predictive techniques accurately. The doctrine reflects the mathematical foundation of traditional astrology.
