Proclus: Commentary on Plato's Timaeus, Vol. II

PRAEFATIO Preface

...[so that] words may be divided according to the ancient custom: ἀπέβλεπεν he looked away, ἐξῆπται is suspended from, ἐπεχείρησεν he attempted, κατηγορήσαντι to the accuser, συγκαθιδρύων establishing together, μετουσία participation, παρίστησιν he presents, προσέθηκε he added, συνυπάρχειν to coexist, ὑπάρχον existing, ὡσαύτως likewise. γίνομαι I become and γινώσκω I know, and the Byzantine form γεννητός begotten are written everywhere against CM, from which it also departs by not eliding vowels at the end of words. Errors due to itacism the pronunciation of certain vowels and diphthongs as 'i' and improper word division are rare; the one defect I have sensed bears the traces of an uncial a majuscule script style archetype.
The numbers owed to a very recent hand, which you read as 55 (fol. 19r), 206 (fol. 60u), 234 (fol. 70u), 314 (fol. 103r), 44[0] (fol. 156r), pertain to the pages of the Paris codex 1838 (D). The Vatican Palatine 121 appears to be its sibling.
I examined them in Paris in 1898, and in Munich in 1901.

N NEAPOLITANVS BORBONICVS III D 28 (cf. Cyrillus II p. 419) of square format (24.9 x 17.9 cm), paper lit. "bombycinus," referring to cotton paper, 164 folios, i.e., 20 quaternions, to which four leaves are attached (not a binion). This codex, copied in 1314, contains the first and second books of the commentary, preceded (fol. 1r–6u) by On the Soul of the World and Nature by Timaeus of Locri. Not even this book is free of a large lacuna; for it lacks p. 250, 30 "the one not knowing but" up to p. 254, 13 "the ever-existing." The same passages as in folio 63 of the Marcian codex 190, being previously omitted (fol. 62u), were written separately by the first hand from the others, joined to the preceding text with a ζ/ο note (cf. p. XIX).
On fol. 164r the following subscription is read:
† The present book was completed by the hand of me, John Kartares, in the month of April, 12th day, in the year 6822 Byzantine dating.
Of Antonio Seripando brother of Cardinal Hieronymus Seripando; see Tiraboschi, Letteratura ital. 14 Tom. VII part. I 327ff from the testament of Janus Parrhasius see Tiraboschi l.c. 210, 1498.
The one who prepared the copy of this book attempted—sometimes not unsuccessfully, more often too boldly—to correct the Proclian text, which was slipping more and more, as well as the errors of the common archetype by his own effort.
