Risālah dar hayʼat. [Sharḥ-i Risālah dar hayʼat]
A Persian manuscript commentary on ʻAlī Qūshjī's treatise on astronomy (Risālah fī al-hayʼah), copied around 1700, probably in Ottoman Turkey, for scholars and students of mathematical astronomy. Pages carry nastaʻlīq text in black and red around inked diagrams of circles, shaded half-dark spheres showing lunar phases and eclipses, and a title page stamped with round ownership seals.
