Abu al-Saqr Abd al-Aziz Ibn Uthman Ibn Ali al-Qabisi l-Mawsili, generally known as Al-Qabisi, (Latinised as Alchabitius or Alcabitius), and sometimes known as Alchabiz, Abdelazys, Abdilaziz (Arabic: 'Abd al-Azîz, عبدالعزيز), (died 967) was an Arabianastrologer and mathematician.
Alchabitius is best known for his treatise on judicial astrology, Introduction to the Art of Judgments of the Stars. This was dedicated to the Emir of Aleppo, Prince Sayf al-Dawla, and survives in at least twenty-five Arabic manuscripts, and over two hundred manuscripts of its Latin translation, with twelve printed editions of the Latin work between 1473 and 1521.:1 The Arabic text has received at least three Latin translations, which attracted several commentaries and were, in turn, translated into other European languages. In the 12th century it was translated by Johannes Hispalensis. In 1512 it was published by Melchiorre Sessa in Venice, Italy. The 1473 copy, and others up until 1521, features writing about Alchabitius by John of Saxony.
