In this research, we propose an analysis and a critical edition of part of the "corpus bunianum": Šams al-maʿārif wa-laṭāʾif al-ʿawārif (The Sun of Knowledge and the ExquisiteGraces) in its short version (the supposedly more ancient one), al-Lumʿa l-nūrāniyya (The Luminescent Glow) and other treaties that have been used to write down the Šams al-maʿārif. Editing these texts corresponding to the "historic core" of this vast corpus highlights the oldest parts of the works attributed to al-Būnī and the influences that contributed to the formation of an Islamic magic, referring not only to Greek authorities, Indian, Mesopotamian, etc.., but also to the Qurʾān, the prophetic tradition and magical, mystical and Kabbalistic Jewish, Christian and Muslim traditions.Closely linked to realms of power, this magical literature also contributes to their splendour andreflects their evolution.
