He was one of the first scholars to recognise prehistoric stone tools as human-made rather than natural, or mythologically created 'ceraunia' or 'glossopetri' - 'thunderstones'. ==Biography== Mercati was born in San Miniato, Tuscany, the son of Pietro Mercati, physician to Popes Pius V and Gregory XIII. He was educated at the University of Pisa, where he took degrees in medicine and philosophy. He was interested in natural history, mineralogy, palaeontology, medicine, and botany, 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 flint and that they had been chipped all over by another stone. By their shapes, Mercati deduced that the stones were intended to be hafted. 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 Three-age system of Lucretius, which described a succession of periods based on the use of stone (and wood), bronze and iron respectively. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Michele Mercati」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
