R in his “Monumenta sacra inedita,” vol. ii, with a facsimile: the amended readings, together with the newly-discovered variations in chh. vi. 31-36, 39, vii. 44, 46, 47, are inserted in the eighth edition of his Greek Testament. In this palimpsest as at present bound up in the Museum the fragments of St. Luke end on f. 48, and the rest of the Greek in the volume is in later, smaller, sloping uncials, and contains propositions from the tenth and thirteenth books of Euclid. On the critical character of the readings of this precious fragment we shall make some comments below. S. CODEX VATICANUS 354 contains the four Gospels entire, and is amongst the earliest dated manuscripts of the Greek Testament (p. 41, note 2). This is a folio of 234 leaves, written in large oblong or compressed uncials: the Epistle to Carpianus and Eusebian canons are prefixed, and it contains many later corrections (e.g. Luke viii. 15) and marginal notes (e.g. Matt. xxvii. 16, 17). Luke xxii. 43, 44; John v. 4; vii. 53-viii. 11 are obelized. At the end we read ἐγράφει ἡ τιμία δέλτος αὕτη διὰ χειρὸς ἐμοῦ Μιχαὴλ μοναχοῦ ἁμαρτωλοῦ μηνὶ μαρτίω α´. ἡμέρα ε´, ὡρα ϛ´, ἔτους ςυνζ. ινδ. ζ´: i.e. A.D. 949. “Codicem bis diligenter contulimus,” says Birch: but collators in his day (1781-3) seldom noticed orthographical forms or stated where the readings _agree_ with the received text, so that a more thorough examination was still required. Tregelles only inspected it, but Tischendorf, when at Rome in 1866, carefully re-examined it, and has inserted many of its readings in his eighth edition and its supplementary leaves. He states that Birch’s facsimile (consisting of the obelized John v. 4) is coarsely executed, while Bianchini’s is too elegant; he made another for himself.
