First part of Book I (I.1-14 in Heiberg’s edition) translated from the Greek in 1620 by John Bainbridge, who had been elected by Henry Savile the first Savilian Professor of Astronomy at Oxford in 1619. Bainbridge published the translation together with the Greek original text in two columns. Chapters are numbered as follows: prologue (1), celestial circles (2), planetary periods (3), Sun and fixed stars (4), Moon (5), Mercury (6), Venus (7), Mars (8), Jupiter (9) and Saturn (10).

Note MS Dublin, TC, 794 (D.3.24), s. XVII, f. 1r-3v, contains John Bainbridge’s Oratio de Ptolomaei hypothesibus (see P. O. Kristeller, Iter Italicum, III, London-Leiden, 1983, 193). I have not seen this manuscript.
