The work was apparently quite popular, as numerous manuscript copies are known to exist, including another in the Special Collections Library (Isl. Ms. 670). Finely illuminated and bound in full leather, the present copy of the first section of the treatise was likely quite a valuable possession of its former owners, many of whom are identified in inscriptions and seal impressions on the opening and closing folios. A few of them annotated the volume with glosses in the margins of the opening sections and excerpts from other texts on the closing folios.
