St. Ambrose having discovered the bodies of SS. Cosmas and Damian, a.d. 389, placed them under the right side of the altar in his basilica, and desired that he should be himself buried near them to the left, which was done a.d. 397. In the year 835 the Archbishop of Milan, Angilbert II., caused a large porphyry sarcophagus to be made in which he laid the body of St. Ambrose between the other two under the altar. In 1864 some excavations and repairs revealed in situ a magnificent sarcophagus nearly four and a half feet in length, three in width, and nearly two in height, without the covering, placed lengthwise. Further excavations brought to view two other tombs, one to the right and one to the left, lined with marble and placed east and west, not as the sarcophagus, north and south. In the one to the left were a few pieces of money, one of Flavius Victor, one of Theodosius, with some fragments of cloth of gold and other things. These were evidently the original resting-places of St. Ambrose and of SS. Cosmas and Damian, and the sarcophagus that constructed under Lothair, a.d. 835, by Angilbert.
