Ar-a-bic parts
Phonetic: /ˈær.ə.bɪk pɑːrts/
In Medieval astrology, Arabic Parts are calculated points derived from mathematical relationships between planets, angles, and other significant chart positions.
These points, also called lots, were inherited from Hellenistic astrology and greatly expanded in Arabic and Medieval astrological traditions. Each part corresponded to a specific topic, such as fortune, marriage, children, illness, travel, or death, and was calculated using established formulas. Medieval astrologers interpreted the sign, house placement, ruler, and aspects of a part to refine judgment concerning the matter it represented. Arabic Parts became an important component of natal, horary, and predictive astrology.
