al-Zīj al-`Alā’ī, composed in Arabic by `Abd al-Karīm al-Shirwānī al-Fahhād (mid-12th c.), but no longer extant [?]. Chioniades (d. Trebizond, ca 1320) studied astronomy and astrology with Shams al-Dīn al-Bukhārī (mid to late 13th c) at Tabrīz (and who is cited in the zīj); Chioniades translated the text into Greek.
