“Kitâb fîmâ Yehtâcü Ýleyhi’s-Sâni‘ min A‘mâli’l-Hendese” Baþlýklý Eserin Ebü'l-Vefâ el-Bûzcânî'ye Âidiyetinin Ýsbatý Meselesi

This research is aiming to study a rare manuscript of al-Farabi called Kitab al-?iyal al-ru?aniyah wa-al-asrar al-?abi‘iyah fi daqa’iq al-askhal al-handasiyah in order to proof that this manuscript is merely a copy of The work of Abu al-Wafa’ Muhammad ibn Muhammad al-Buzjani (940-998) with a slightly different title: Kitab fima yahtaj ilayh al-sani’ mina al-a’mal al-handasiyah (The book about what the craftsman needs of geometrical constructions). So it seems that this is a work by al-Farabi, and whatever the exact authorship we found out that it merits further study. The treatise of al-Farabi contains the foreword and 10 books (maqalat). All 10 books are included as a whole into Abu al-Wafâ’s treatise: The first book (makala) coincides with the second half of the II chapter of Abu al-Wafâ from 9 proposition to the end, the II-IX books entirely coincide with III-X chapters of Abu al-Wafâ, The X book coincides with the first half of the XI chapter of Abu al-Wafâ. So we find that it resembles the work of Abu al-Wafa’ al-Buzjani and we tryed to proof our vue with some proofs.
