Matlau’n-Nujum Project involves the critical edition and examination of the scholarly value of Nesefi’s work, which has not yet been utilized by the academic community and of which only two copies have survived to the present day. Initially, the project will produce a critical edition of the work compiled by Najm al-Din Umar al-Nasafi. Subsequently, it is planned to evaluate this book, which brings together treatises on sciences existing in the sixth century AH, as a source and to interpret each treatise.
