Arabic parts

In astrology, the Arabian/Arabic parts or lots are constructed points based on mathematical calculations of three horoscopic entities such as planets or angles.

After the fall of the Roman Empire, all of the classical legacy, including astrology, fell to the Abbasid Arabs and Persians.

Beginning in the tenth century, many Arabic manuscripts were translated into Latin, becoming the means by which Classical astrology found its way back to Europe.

By the time of William Lilly (XVII century), only the Lot of Fortune continued to be used by astrologers, although in a manner that would be considered strange by ancient practitioners.

[2] This set of lots appears in the work of the 4th century astrologer Paulus Alexandrinus, as well as in his later commentator Olympiodorus the Younger.
