, and produced a book on these subjects entitled the '' Metallotheca'', which was not published until 1717. Mercati collected curious objects - fossils, minerals and so on - as well as 'ceraunia' or 'thunderstones'. Mercati was particularly interested in Ceraunia cuneata, "wedge-shaped thunderstones," which seemed to him to be most like axes and arrowheads, which he now called ceraunia vulgaris, "folk thunderstones," distinguishing his view from the popular one. Mercati examined the surfaces of the ceraunia and noted that the stones were of

He then showed the similarities between the 'ceraunia' and artifacts from the New World that explorers had identified as implements or weapons. Mercati posited that these stone tools must have been used when metal was unknown and cited Biblical passages to prove that in Biblical times stone was the first material used. He also revived the
