"Thus, as has been often said, revealed religion has no greater foe than ignorance. Far from making it _her ally_, as men who deny the testimony of all ages have not blushed to assert, she cannot but glory in the advance of the sciences. She has always favoured them, and it is chiefly owing to her influence, that they have been preserved in the midst of the barbarism from which she has rescued us. Thus the progress of true science, _the progress of light_ (to use a legitimate though often abused expression,) far from being at variance with revealed religion, as its enemies have represented,--far from being dangerous to it, as some of its disciples have appeared to fear, tends, on the contrary, each day to strengthen its claims upon all enlightened minds, and to prove, in opposition to the pride of false science, that this divine religion, confirmed as it is by all the truths to which the human mind attains, _is the truth of the Lord which endureth forever_." We have ventured upon this protracted notice of the Essay of Mons. Greppo, because the subject itself is one of gratifying pursuit even to the mere scholar, but still more because it is vitally connected with the evidences of revealed religion in which we hope that none of our readers are altogether uninterested. There is in the Essay, no question as to any of the minor points of the Christian faith,--there is here nothing but what all may peruse with satisfaction. The question is one entirely connected with evidence; and science and literature are pressed fairly into the service of truth. The work is peculiarly valuable, because it is the only work connected with the labours of Champollion which has been made to wear an English dress. The works of both the Champollions are locked up in a foreign language from most of our readers; and we fear that the time will not soon come when there will be sufficient encouragement either to translate or publish in this country the splendid volumes of these brothers, who are, by their discoveries, raising up for France the gratitude of the world. Until there shall be liberality enough in our republic of letters, to enable us to possess these works, with all their riches of illustration, and thus have ancient Egypt brought to the inspection of American eyes, we would recommend the work of Mons. Greppo, as the best, and indeed only substitute at present known, always excepting the pages of our own journal. It is needless to say, that the merits of the translation cannot be questioned, after the testimonials furnished by the learned Dr. Stuart; without the advantage of comparing it with the original, we can speak of its excellence relatively, for the style is clear, concise, and classical.
