Latin Equivalents of Brain Membranes: A Solid Proof of Connection between Liber Pantegni by Constantine the African and Kāmil Al-Ṣināʻa Al-Ṭibbīya by 'Ali ibn al-'Abbas al-Mağūsī

'Ali ibn al-'Abbas al-Mağūsī, one of the prominent physician during Būyid dynasty (also called Buwayhid), lived between the lifetime of Razes and Avicenna the two legendary characters of medicine. He wrote a medical encyclopedia for the royal library of Aḍud al-Dawla (949-983) and named it Kāmil al-Ṣināʿa al-Ṭibbīya (i.e., complete medical art). This book could be considered the first medical compendium scientifically written during the Islamic era because it criticizes the prior books and justifies the necessity of the present work (i.e., Kāmil Al-Ṣināʻa Al-Ṭibbīya). The first Latin translation of this book has been performed by Constantine the African in the 11th century under the name of Liber Pantegni. He did not mention the real author's name and attributed it to himself. He removed all signs in the book that could have any reference to its origin (as he did in other cases). Despite this immoral act and in addition to all studies carried out during the last two centuries regarding the Constantine plagiarism, the present study presented clear evidence on the denomination of meninges indicating that Liber Pantegni is, in fact, Kāmil Al-Ṣināʻa Al-Ṭibbīya.
