It has a deep connection with hand-polished porcelain that appeared in mainland Greece, Italy and Sicily at the same time. There is no precedent for pottery in these areas, and Dege-Jarkozy demonstrated that these pottery finally came from the hometown of traditional pottery-the middle reaches of the Danube River in Central Europe. The crude products of the period represented by the seventh floor Trojan 1 can be considered as a tool to identify the invaders of the period represented by the seventh floor Trojan. They are a group of people who passed through Bont, hoels, at the end of their migration from the central Danube to the Turkish Balkans. Similar people may be related to many major Mycenae settlements in the Peloponnesian Peninsula. However, it must be admitted that there are some defects in this reconstruction process. One of them is that the number of rough products existing in the period represented by the 7th floor of Troy 1 is relatively small compared with those hand-made polished pottery existing in Mycenae residential area in the Greek mainland during the period of Lhiiiic. Did these potters really play an important role in the political and military history of the late Bronze Age in the Aegean Sea, as some authorities said?
