Al-cha-bi-tius’ meth-od
Phonetic: /æl.kəˈbɪt.i.əs ˈmɛθ.əd/
Alchabitius’ method is a Medieval house division system developed from the astronomical work of Alchabitius and widely used in Medieval and early Renaissance astrology.
This method divides the space between the angles of the chart according to the semi-arcs of the celestial sphere. It became especially influential in Latin Europe after the translation of Arabic astrological texts. Medieval astrologers used the Alchabitius system for natal, horary, and predictive astrology because it provided a structured approach to determining house cusps. Its popularity reflects the strong influence of Arabic astronomical techniques on Medieval astrological practice.
