Π. CODEX PETROPOLITANUS consists of 350 vellum leaves in small quarto, and contains the Gospels complete except Matt. iii. 12-iv. 18; xix. 12-xx. 3; John viii. 6-39; seventy-seven verses. A century since it belonged to Parodus, a noble Greek of Smyrna, and its last possessor was persuaded by Tischendorf, in 1859, to present it to the Emperor of Russia. Tischendorf states that it is of the age of the later uncials (meaning the ninth century), but of higher critical importance than most of them, and much like Cod. K in its rarer readings. There are many marginal and other corrections by a later hand, and John v. 4; viii. 3-6 are obelized. In the table of κεφάλαια before St. Mark, there is a gap after _λϛ_: Mark xvi. 18-20; John xxi. 22-25 are in a later hand. At the end of St. Mark, the last section inserted is _σλδ_ by the side of ἀναστὰς δέ ver. 9, with _η_ under it for the Eusebian canon. Tischendorf first used its readings for his Synopsis Evangelica 1864, then for the eighth edition of his Greek Testament 1865, &c. This manuscript in the great majority of instances sides with the later uncials (whether supported by Cod. A or not) against Codd. אBCD united. Σ. COD. ROSSANENSIS, like Cod. N described above, is a manuscript written on thin vellum leaves stained purple, in silver letters, the first three lines of each Gospel being in gold. Like Cod. D it probably dates from the sixth century, if not a little sooner, and is the earliest known copy of Scripture which is adorned with miniatures in watercolours, seventeen in number, very interesting and in good preservation. The illustrated Dioscorides at Vienna bears about the same date. Attention was called to the book by Cesare Malpica in 1846, but it was not seen by any one who cared to use it before March, 1879, when Oscar von Gebhardt of Göttingen and Adolf Harnack of Giessen, in their search for codices of Hippolytus, of Dionysius of Alexandria, and of Cyril of Jerusalem, described by Cardinal Sirlet in 1582, found it in the Archbishop’s Library at Rossano, a small city in Calabria, and published an account of it in 1880 in a sumptuous form, far more satisfactory to the artist than to the Biblical critic. Their volume is illustrated by two facsimile leaves, of one of which a reduction may be seen in our Plate xiv, No. 43. A copy of the manuscripts was published at Leipsic in 1883 with an Introduction by Oscar von Gebhardt, the Text being edited by Adolf Harnack(204). The page we have exhibited gives the earliest MS. authority, except Φ, for the doxology in the Lord’s Prayer, Matt. vi. 13. The manuscript is in quarto, 13-½ inches high by 10-¼ broad, and now contains only the Gospels of St. Matthew and St. Mark on 188 leaves of two columns each, there being twenty lines in each column of very regular writing, and from nine to twelve letters in each line. It ends abruptly at Mark xvi. 14, and the last ten leaves have suffered from damp; otherwise the writing (especially on the
