Hallstatt The introduction of iron into Italy has often been attributed to the Etruscans, who were thought to have brought the knowledge from Lydia. But the most abundant remains of the Early Iron Age are found not in Tuscany, but along the coasts of the Adriatic[102], showing that iron followed the well-known route of the amber trade, thus reaching Central Europe and _Hallstatt_ (which has given its name to the Early Iron Age), where alone in Europe the gradual transition from the use of bronze to that of iron has been clearly traced. W. Ridgeway[103] believes that the use of iron was first discovered in the Hallstatt area and that thence it spread to Switzerland, France, Spain, Italy, Greece, the Aegean area, and Egypt rather than that the culture drift was in the opposite direction. There is no difference of opinion however as to the importance of this Central European area which contained the most famous iron mines of antiquity. Hallstatt culture extended from the Iberian peninsula in the west to Hungary in the east, but scarcely reached Scandinavia, North Germany, Armorica or the British Isles where the Bronze Age may be said to have lasted down to about 500 B.C. Over such a vast domain the culture was not everywhere of a uniform type and Hoernes[104] recognises four geographical divisions distinguished mainly by pottery and fibulae, and provisionally classified as Illyrian in the South West, or Adriatic region, in touch with Greece and Italy; Celtic in the Central or Danubian area; with an off-shoot in Western Germany, Northern Switzerland and Eastern France; and Germanic in parts of
