The chromo-lithographic press, established at Rome by the munificence of Pius IX., has issued its first publication, four sheets in large folio, _Imagines Selectae Deiparae Virginis in Caemeteriis Suburbanis Udo depictae_, with about twenty pages of text from the pen of the Cavaliere G. B. de Rossi. The subject and the author are amply sufficient to recommend them to the Christian archaeologist, and the work of the artists employed is in every way worthy of both. It is by no means an uncommon idea, even among Catholics who have visited Rome and _done_ the catacombs, that our Blessed Lady does not hold any prominent place in the decorations of those subterranean cemeteries. Protestant tourists often boldly publish that she is nowhere to be found there. The present publication will suffice to show, even to those who never leave their own homes, the falsehood of this statement and impression. De Rossi has here set before us a selection of four different representations of Holy Mary, as she appears in that earliest monument of the Christian Church; and, in illustrating these, he has taken occasion to mention a score or two of others. Moreover, he has vindicated for them an antiquity and an importance far beyond what we were prepared to expect; and those who have ever either made personal acquaintance with him, or have studied his former writings, well know how far removed he is from anything like uncritical and enthusiastic exaggerations. Even such writers as Mr. Burgon ("Letters from Rome") cannot refrain from bearing testimony to his learning, moderation, and candor; they praise him, often by way of contrast with some Jesuit or other clerical exponent of the mysteries of the catacombs, for all those qualities which are calculated to inspire us with confidence in his interpretations of any nice points of Christian archaeology. But we fear his Protestant admirers will be led to lower their tone of admiration for him, and henceforward to discover some flaw in his powers of criticism, when they find him, as in these pages, gravely maintaining, concerning a particular representation of the Madonna in the catacombs, that it is of Apostolic, or quasi-Apostolic antiquity. It is a painting on the vaulted roof of an _arcosolium_ in the cemetery of St. Priscilla, and it is reproduced in the work before us in its original size. The Blessed Virgin sits, her head partially covered by a short slight veil, holding the Divine Infant in her arms; opposite to her stands a man, holding in one hand a volume, and with the other pointing to a star which appears between the two figures. This star almost always accompanies our Blessed Lady in ancient paintings or sculptures, wherever she is represented either with the Magi offering their gifts, or by the manger's side with the ox and the ass; but with a single figure, as in the present instance, it is unusual. Archaeologists will probably differ in their
