This is the Commentary of Galen on the Book of Hippocrates On
Prognostics (Tafsīr Jālīnūs li-kitāb Buqrāṭ fī taqdimat
al-maʿrifah). This copy is unsigned and undated. The appearance of
the paper, ink, and script suggest a dating of before the end of
the thirteenth century, possibly in Syria or Egypt.
