examined it in 1809, he has the merit of first placing it in the paramount rank it still holds as one of the oldest and most venerable of extant monuments of sacred antiquity. His conclusion respecting its date, that it is not later than the middle of the fourth century, has been acquiesced in with little opposition, though Tischendorf declares rather pithily that he holds this belief “non propter Hugium sed cum Hugio” (Cod. Ephraem. Proleg. p. 19). Some of his reasons, no doubt, are weak enough(143); but the strength of his position depends on an accumulation of minute particulars, against which there seems nothing to set up which would suggest a lower period. On its return to Rome, this volume was no longer available for the free use and reference of critics. In 1843 Tischendorf, after long and anxious expectation during a visit to Rome that lasted some months, obtained a sight of it for two days of three hours each(144). In 1844 Edward de Muralt was admitted to the higher privilege of three days or nine hours enjoyment of this treasure, and on the strength of the favour published an edition of the New Testament, _ad fidem codicis principis Vaticani_, in 1846. Tregelles, who went to Rome in 1845 for the special purpose of consulting it, was treated even worse. He had forearmed himself (as he fondly imagined) with recommendatory letters from Cardinal Wiseman, and was often allowed to _see_ the manuscript, but hindered from transcribing any of its readings(145). What the Papal authorities would not entrust to others, they had at least the merit of attempting and at length accomplishing themselves. As early as 1836 Bishop Wiseman announced in his Lectures on the Connection between Science and Revelation, vol. ii. pp. 187-191, that Cardinal Mai, whose services to classical and ecclesiastical literature were renowned throughout Europe, was engaged on an edition of the Codex Vaticanus, commenced under the immediate sanction of Pope Leo XII (1823-29). As years passed by and no such work appeared, adverse reports and evil surmises began to take the place of hope, although the Cardinal often spoke of his work as already finished, only that he desired to write full Prolegomena before it should appear. In September 1854 he died, honoured and ripe in years; and at length, when no more seemed to be looked for in that quarter, five quarto volumes issued from the Roman press in 1857, the New Testament comprising the fifth volume, with a slight and meagre preface by the Cardinal, and a letter to the reader by “Carolus Vercellone, Sodalis Barnabites,” which told in a few frank manly words how little accuracy we had to expect in a work, by the publication of which he still persuaded himself he was decorating Mai’s memory “novâ usque gloriâ atque splendidiore coronâ” (tom. i. p. iii). The cause of that long delay now required no explanation. In fact so long as Mai lived the edition never would have appeared; for though he had not patience or special skill
