May 2021 Nadine Löhr published a transcription of al-Battānī’s Sharḥ Kitāb al-Arbaʿ, the earliest extant commentary on Ptolemy’s Tetrabiblos. The text is accessible on the web page of Ptolemaeus Arabus et Latinus at the Bavarian Academy of Sciences and based on manuscript San Lorenzo de El-Escorial árabe 969. Correspondences to the only other extant witness Berlin Sprenger 1840 are indicated.
