SVPPLEMENTVM CAPITIS PRIMI SUPPLEMENT TO CHAPTER ONE

VATICANVS PALATINVS graec. 121 (cf. H. Stevenson, Codices manuscripti Palatini graeci Bibliothecae Vaticanae p. 57) of largest format (30.7 x 24.7 cm), paper, 16th century, 194 leaves (23 quaternions, 1 trinion $\bar{ι}\bar{δ}$, 1 binion leaf 191—194). It contains the first book of the commentary, damaged by the same lacuna (leaf 187r) as codex P. Since it is also missing text in another place (leaf 192u) — for p. 191, 20 "an image of operation" up to p. 203, 7 "the Athenians" are missing — which is half of the former lost part, one might surmise that two quaternions, or one, of the archetype have perished.

I would hold this book to be a sibling of codex P (p. 68, 20 heracleian and p. 88, 16 offerings match P), not a descendant (p. 112, 28 through these is contrary to P).

I examined this in Rome in 1900.

MARCIANVS graec. 190 (cf. Zanetti p. 108) parchment, 31.4 x 22.5 cm, 14th century, 27 quinternions, to which correspond 270 leaves of 37 lines. Four blank leaves precede the first quinternion; following the last are leaves 271r—281r (to which seven blank leaves are attached), exhibiting Proclus's commentary on the First Alcibiades, which the same hand, which you can easily recognize from the scholia added to the Timaeus commentary, wrote out less diligently with slightly lighter ink. On the back of the first blank leaf, these things have been written by a recent hand:
