A translation of the complete work (with Book III in Nicolaus Cabasila’s version, Book V in Pappus of Alexandria’s version and Book XI missing, see C.1.30) by Jerόnimo Muñoz in 1582, when he was professor of astronomy (‘cathedraticus astrologie’ or ‘professor astrologie’, as he calls himself in the colophon and in several places in the text) at the University of Salamanca. The only known manuscript is Muñoz’s autograph copy, which includes his corrections, notes, additions and sometimes extensive commentary. These are variously referred to by the words ‘Interpres’ or ‘Munos’ written in the margin, or as ‘Propositio addita ab interprete’ (55v), ‘Interpretis addito’ (71v), ‘Finis commetariorum Theonis et additionum Hieronymi Munos interpretis’ (74v), ‘Commentaria Hieronymi Munos in 6 caput libri 4…’ (190r), etc. See also the description of the manuscript. Muños annotated the manuscript beyond 1582, as shown by his observations dated 1583 (271r), 1584 (155r), 1585 (171v) and 1589 (172v).
