 Based on archaeological findings in the Middle East , in particular physical artifacts , textual references , inscriptions and wall paintings , it appears that Mycenaean Greeks achieved strong commercial and cultural interaction with most of the Bronze Age people living in this region : Canaanites , Kassites , Mitanni , Assyrians , and Egyptians . The 14th century Uluburun shipwreck , off the coast of southern Anatolia , displays the established trade routes that supplied the Mycenaeans with all the raw materials and items that the economy of Mycenaean Greece needed , such as copper and tin for the production of bronze products . A chief export of the Mycenaeans was olive oil , which was a multi @-@ purpose product .
