mantle indicate the commencement of Byzantine art." The great rival to the "Codex Cottonianus Geneseos" is the "Codex Vindobonensis Geneseos," which consists of twenty-six leaves with eighty-eight miniatures. It forms one of the four great lions of the Vienna Imperial Library. These two remarkable versions of Genesis are supposed to be of nearly equal date, and correspond as to the character of the truly antique miniatures very fairly; the fact, however, of the text of the English version being in black ink with very regularly-formed letters, while that of the Vienna one is, for the most part, written in gold and silver, and in less evenly-distributed characters, induces a fair presumption in favour of the greater antiquity of the Cottonian fragments. In the more gorgeous details of the Vienna Genesis, coupled with its square and unadorned classic pictures, we may thus clearly recognize the transition from our first or Latin class of ancient illumination, to our second or purely Byzantine style. We especially designate this class as "Byzantine," because as art in illumination, as in all other branches, declined in the seven-hilled city, it rose in the seat of empire founded in the East by the first great Christian emperor. It is true that ideal art degenerated almost contemporaneously in the capitals of both empires; but in decorative art, at least, there can be no question but that Byzantium gained, as Rome lost, ground. The former no doubt drew fresh inspiration from her close intercourse with the Persian and other nations of the East, while the latter was content to produce little, and that little in slavish reminiscence of the past. Italy no doubt fed the earliest monastic libraries of Western Europe with the quantities of texts of ancient authors we know them to have contained; but we may fairly assume those texts to have been but rarely illustrated, since the original styles of illumination produced in those countries to which the classic volumes travelled, would unquestionably have betrayed an antique influence more strongly than they did, had the means of deriving that influence been brought copiously within their reach. I proceed now to a slight notice of the second class of ancient codices, that on which the ultimate splendour of the Byzantine school was founded. Fortunately, time has spared to our days several brilliant specimens of the richest of these quasi-classic manuscripts. Of such, the principal are, as Sir Frederick Madden observes,[19] "the celebrated Codex Argenteus of Ulphilas, written in silver and gold letters on a purple ground, about A.D. 360, which is, perhaps, the most ancient existing specimen of this magnificent mode of caligraphy; after it, may be instanced the copy of Genesis at Vienna," already mentioned, the Psalter of St. Germain des Prés, at Paris, and the fragment of the New Testament in the Cottonian Library, Titus C. xv., all executed in the 5th and 6th centuries.
