(2) =Geographical.=—Having defined our historical limits, it remains to consider the extent of Greek civilisation during that period, as attested by archaeological or other evidence. Besides the mainland of Greece and the islands of the Aegean Sea, the whole of Asia Minor may be regarded as in a measure Greek, although practically speaking only a strip of territory along the western coast became really Hellenised, and we shall not be concerned with pottery-finds in any other part of the country.[48] To the north-east, Greek colonisation penetrated as far as Kertch and other places in the Crimea, known to the ancients as Panticapaeum and the Bosphoros respectively. In the Eastern Mediterranean the island of Cyprus will demand a large share of our attention. Egypt, again, has yielded large numbers of vases, mostly from the two Greek settlements of Naukratis and Daphnae; and farther to the west along the north coast of Africa was the Greek colony of Kyrene, also a fruitful site for excavators. The rest of the ground is covered by the island of Sicily and the peninsular portion of Italy from Bologna southwards. Greek vases have occasionally turned up in Spain, Gaul (_i.e._ France and North Italy), as at Marseilles (Massilia), where primitive Greek pottery has been found, and also in Sardinia; but the Western Mediterranean sites are chiefly confined to Southern Italy and Etruria. In fact, till recent years these regions were almost our only source of information on Greek pottery, as has already been pointed out. Generally speaking, it may be said that all Greek vases have been found in tombs, but the circumstances under which they have been found differ according to locality. We propose in the succeeding section to say something of the nature of the ancient tombs, and the differences between those of Greece, Cyprus, Italy, and other sites. Of finds on the sites of temples and sanctuaries it is not necessary to say much here; the explanation of such discoveries will receive some attention in Chapter IV., and the individual sites will also be noted in the next section of this chapter. It is a rare occurrence to find complete vases under these circumstances, as they generally owe their preservation to the fact that they have been broken in pieces and cast away as rubbish into holes and pits. The most notable instance is the remarkable series of fragments discovered on the Acropolis at Athens.
