With these stones, in fact, were found numerous bones of great size, which had belonged to unknown creatures. Latin authors speak of similar bones found in Asia Minor, which they took to be those of giants of an extinct race. This belief was long maintained; in 1547 and again in 1667 fossil remains were found in the cave of San Ciro near Palermo; and Italian savants decided that they had belonged to men eighteen feet high. Guicciadunus speaks of the bones of huge elephants carefully preserved in the Hôtel de Ville at Antwerp as the bones of a giant named Donon, who lived 1300 years before the Christian era. In days nearer our own the roost cultivated people accepted the remains of a gigantic batrachian4 as those of a man who had witnessed the flood, and it was the same with a tortoise found in Italy scarcely thirty years ago. Dr. Carl, in a work published at Frankfort5 in 1709, took up another theory, and, such was the general ignorance at the time, he used long arguments to prove that the fossil bones were the result neither of a freak of nature, nor of the action of a plastic force, and it was not until near the end of his life that the illustrious Camper could bring himself to admit the extinction of certain species, so totally against Divine revelation did such a phenomenon appear to him to be. Prejudices were not, however, always so obstinate. For more than three centuries stones worked by the hand of man have been preserved in the Museum of the Vatican, and as long ago as the time of Clement VIII. his doctor, Mercati, declared these stones to have been the weapons of antediluvians who had been still ignorant of the use of metals. During the early portion of the eighteenth century a pointed black flint, evidently the head of a spear, was found in London with the tooth of an elephant. It was described in the newspapers of the day, and placed in the British Museum. In 1723 Antoine de Jussieu said, at a meeting of the _Académie des Sciences_, that these worked stones had been made where they were found, or brought from distant countries. He supported his arguments by an excellent example of the way in which savage races still polish stones, by rubbing them continuously together. A few years later the members of the _Académie des Inscriptions_ in their turn, took up the question, and Mahudel, one of its members, in presenting several stones, showed that they bad evidently been cut by the hand of man. “An examination of them,” he said, “affords a proof of the efforts of our earliest ancestors to provide for their wants, and to obtain the necessaries of life.” He added that after the re-peopling of the earth after the deluge, men were ignorant of the use of metals. Mahudel’s essay is illustrated by drawings, some of which we reproduce (Fig. 1), showing wedges, hammers, hatchets, and flint arrow-beads taken, he tells us, from various private collections.6
