Δ. CODEX SANGALLENSIS, was first inspected by Gerbert (1773), named by Scholz (N. T. 1830), and made fully known to us by the admirable edition in lithographed facsimile of every page, by H. Ch. M. Rettig [1799-1836], published at Zurich, 1836(198), with copious and satisfactory Prolegomena. It is preserved and was probably transcribed a thousand years since in the great monastery of St. Gall in the north-east of Switzerland (Stifts bibliothek, 48). It is rudely written on 197 leaves of coarse vellum quarto, 8-7/8 inches by 7-1/8 in size, with from twenty to twenty-six (usually twenty-one) lines on each page, in a very peculiar hand, with an interlinear Latin version, and contains the four Gospels complete except John xix. 17-35. Before St. Matthew’s Gospel are placed Prologues, Latin verses, the Eusebian canons in Roman letters, tables of the κεφάλαια both in Greek and Latin, &c. Rettig thinks he has traced several different scribes and inks employed on it, which might happen easily enough in the Scriptorium of a monastery; but, if so, their style of writing is very nearly the same, and they doubtless copied from the same archetype, about the same time. He has produced more convincing arguments to show that Cod. Δ is part of the same book as the Codex Boernerianus, G of St. Paul’s Epistles. Not only do they exactly resemble each other in their whole arrangement and appearance, but marginal notes by the first hand are found in each, of precisely the same character. Thus the predestinarian doctrines of the heretic Godeschalk [d. 866] are pointed out for refutation at the hard texts, Luke xiii. 24; John xii. 40 in Δ, and six times in G(199). St. Mark’s Gospel represents a text different from that of the other Evangelists, and the Latin version (which is clearly _primâ manu_) seems a mixture of the Vulgate with the older Italic, so altered and accommodated to the Greek as to be of little critical value. The penmen seem to have known but little Greek, and to have copied from a manuscript written continuously, for the divisions between the words are sometimes absurdly wrong. There are scarcely any breathings or accents, except about the opening of St. Mark, and once an aspirate to ἑπτα; what we do find are often falsely given; and a dot is set in most places regularly at the end of every _Greek_ word. The letters have but little tendency to the oblong shape, but _delta_ and _theta_ are decidedly of the latest uncial type. Here, as in Paul. Cod. G, the mark >>> is much used to fill up vacant spaces. The text from which Δ was copied seems to have been arranged in στίχοι, for almost every line has at least one Greek capital letter, grotesquely ornamental in colours(200). We transcribe three lines, taken almost at random, from pp. 80-1 (Matt. xx. 13-15), in order to explain our meaning:
