Maraldus the Carthusian, who accompanied his abbot Rudolph to the coronation of Roger, King of Sicily, as historiographer, tells us in his _Chronicon_--or perhaps his continuator--how, in 1140, Roger visited Naples, and how there he venerated the relics of the head and of the blood of St. Januarius. The Liquefaction is not mentioned in so many words. But these relics would not have been singled out from all others in the city, and made so prominent, without some special 33 reason--a reason, perhaps, so well known and so obvious that it did not occur to the writer to state it explicitly, any more than to say that the king venerated the relics in the daytime and not at night. The learned and critical Bollandists, who have carefully weighed all that can be said on this question, incline to hold that the Liquefaction commenced somewhere between the years 900 and 1000. Prior to the century between those years, St. Januarius had been ranked among the minor patrons of the church of Naples. After that century, he holds the most prominent place and rank in their calendar. This change is unusual and important, and must have been based on some sufficient reason. The most probable one under the circumstances--if not the only one that can be assigned--is that during that century the Liquefactions became known. The contemporary records of Naples for that time were very few; for it was a period of incessant warrings, devastations, and tumults. Those that did exist probably perished in the not unfrequent destruction of the monastic libraries. Still, some venerable manuscript may even yet come to light, telling us how on some festival day, or day of supplication, the relics were all on the altar, the vials of the blood near to the head; how some of the crowd that prayed before the altar saw that the blood in the vial had become liquid; how the wonderful thing was spoken of and seen by many; how, on other occasions, it occurred again and again; until at last it came to be regularly looked for, as a part, and the most wonderful part, of the celebration. After 1400, the notices of the Liquefaction are more frequent. Æneas Sylvius Piccolomini (afterwards Pope Pius II.) gives an account of it. Robert Gaguin, the old French historian, narrating the journey of Charles VIII. into Italy, mentions his visiting Naples in 1495, and his witnessing and examining this miracle of the Liquefaction. In 1470, Angelo Catone, a physician of Salerno, who devoted the later years of his life to literature and to travelling, has written a brief but clear account of it. Picus de la Mirandola, the wonder of his age, has also left his testimony as an eye-witness. It is needless to say that, since the invention of printing and the multiplication of books, we have numberless accounts of it from travellers and authors, in Latin, Italian, German, Polish, English, French, Spanish, and every language of Europe.
