he could get together were scanty when compared with the materials possessed by scholars of our day and time, and in consequence many of the conclusions to which this pioneer of Catacomb research came to were erroneous.
But in his manner of working Bosio had no successors. As a rule, since that really illustrious scholar and searcher has passed away, alas! a very different method has been with rare exceptions followed by explorers of the Catacombs, and owing to the careless and ill-regulated excavations which have been fitfully carried on during some 200 and more years, irreparable damage has been done, and the losses to this deeply important branch of early Christian history are simply incalculable.
The general results of this unfortunate exploration work in the past have been summarised as follows:
During this long period—roughly from A.D. 1629 to about the middle of the nineteenth century, some 220 years—the chief object and aim of Catacomb exploration were to procure relics; when these were once carried away, no heed was paid to the crypts, or to the streets of graves. The records of the excavations kept were scanty and utterly insignificant, and each Catacomb from which the relics were taken was left in a state of utter ruin and deplorable confusion. The result of these searchings of 220 years has been that few discoveries were made of any real importance to early Christian history or archæology. At last De Rossi, in the middle years of the nineteenth century, took in hand seriously the study and scientific exploration of the vast Christian necropolis of Rome.
De Rossi was the friend and pupil of Father Marchi, an indefatigable student of the Catacombs who was really impressed with the possibilities of a more careful exploration than had hitherto been undertaken. Marchi's real title to honour will ever be that he imbued his pupil with a passionate love of the work to which he has devoted a long and strenuous life.
The great City of the Dead, largely thanks to De Rossi's lifelong labours, is to us something far more than a vast museum of inscriptions and memorials, the work of the Christian congregations in Rome during the first two and a half
