In the earlier numbers of the _Bollettino_ for the present year there is a very interesting account of the recent discoveries in the Ambrosian basilica of Milan, where there seems no room to doubt but that they have brought to light the very sarcophagus in which the relics of the great St. Ambrose, as well as those of the martyrs Sts. Gervasius and Protasius, have rested for more than ten centuries. The history of the discovery is too long to be inserted here, and too interesting to be abridged. One circumstance, however, connected with it is too important to be omitted. The sarcophagus itself has not yet, we believe, been opened; but, from the two sepulchres below and on either side of it, where the bishop and the martyrs were originally deposited, and where they remained until their translation in the ninth century, many valuable relics have been gleaned. We will only mention one of them--viz., portions of an _ampulla_ such as are found in the catacombs, and concerning which Dr. Biraghi, the librarian of the Bibliotheca Ambrosiana (to whose zeal we are indebted for the whole discovery, and for the account of it to his learning), assures us that it has been subjected to a chemical examination, and is shown to have contained blood. This, as De Rossi truly remarks, is the most notable instance which has yet come before us of this _ampulla_ having been placed in the sepulchre of famous and historical martyrs, and it is of very special importance as throwing a flood of light on those words of St. Ambrose about these relics so often quoted in the controversy on this subject--_Sanguine, tumulus madet; apparent cruoris triumphales notae; inviolatae reliquiae loco suo et ordine repertae_. And it is certainly singular that this discovery should have been made at a moment when the validity of these _ampullae_, as sure signs of martyrdom, has been so much called in question. The Sacred Congregation of Rites had only recently reaffirmed their former sentence on this matter; and this fact now comes most opportunely from Milan to add further weight to their decision, by giving a historical basis to an opinion which before had been thought by some rather to rest upon theory and conjecture. It will go far, we should think, toward _rehabilitating_ in the minds of Christian archaeologists the pious belief of former ages upon this subject, wherever it may have been shaken. ------ {134} MISCELLANY.
