For our purpose it is quite unnecessary to discuss the difficult and debated question as to where the use of copper and bronze originated. It is sufficient to note that the island of Cyprus, placed near early centres of civilisation seems to have been the region from which a knowledge of the pure metal and of its more useful alloy radiated over the Mediterranean and ultimately over Europe generally. It is more than probable that the use of copper or of bronze spread faster than the knowledge of the method of producing either. It is at least clear that in many cases the Stone and Bronze Ages co-existed, suggesting that the new type of implements was at first very difficult to obtain. No doubt for long ages they occupied the position which firearms long occupied among savage races, and which they still occupy among those most remote from civilisation. In Cyprus itself very few stone implements occur, suggesting that the Stone Age was very short, and rapidly gave place to a metal one. We do not know how the discovery was made that the addition of tin improved copper for human purposes. Bronzes of very varying composition have been found, including many which contain antimony, a somewhat rare metal, still employed in making many useful alloys. It is suggested that the first smiths tried a great number of combinations before they found one which was satisfactory, and finally fixed upon tin as the most suitable addition. The next point of interest is the source of the tin. This is a question of great interest, for long after iron had been used, and used extensively in the manufacture of implements, the demand for bronze continued, for the iron, even of late Roman days, was very costly and probably very troublesome to make. Bronze also became of importance in connection with the coinage of civilised nations. Tin is not a very abundant metal, and it is rare in the Mediterranean. The deposits which were utilised by the first makers of bronze have doubtless completely disappeared, for from the early days of civilisation the tin deposits even of Far Britain were sought. Within the Mediterranean region at the present time only one tin deposit of any importance is known. This occurs in the village of Montecatini, which is situated near Volterra in Italy, in the ancient Etruria. It perhaps played a part in connection with the development of the civilisation of ancient Etruria. Outside of the Mediterranean the main deposits of tin in Europe occur, or occurred, in three separate areas, which formed as it were three stages in one journey, and whose position certainly made them a factor in promoting the spread of Mediterranean culture to the north-west.
