Binding leaves	(ii-xxvi, 175-98) inserted blank leaves. At xxvii is a Dutch astronomical table (s. 15) and at 174v the beginning of a list of the contents of Haly Aben Ragel ("Hali Habenragels zone") de Iudiciis Astrorum, with translation of most of the Latin translator's preface, in Dutch. The author's name Abû'l-Hasan `Alîl-Hasan `Alî ibn Abî'l-Rijâl; this is part of a Dutch translation (s. 15/II) of the Latin version (by Aegidius de Thibaldis of Parma and Petrus de Regio) of the Spanish version by Judah ben Moses. The fly-leaves are from s. 15 ex. parchment Latin theological roll of the dialogue between the Virgin and "Peccator", written in the Netherlands; ends "nullus fere quantumque peruersus nobis remanere possit".
Cover	Stamped leather with clasp fittings (but the leather clasps are lost), Netherlandish work, contemporary. The leather boards in the binding had done service for another binding of similar date and style.
