Bronze was imported to Scandinavia from the East Mediterranean. This trading started about 1750 BC. At just the same time amber from the Baltic started to appear in Mycenaean and Minoan graves. This gives evidence of active trading between the Mediterranean and Scandinavia. The sudden appearance of picture of large ships cut into bedrock surfaces and blocks at about the same time suggests that this trading took place via visitors arriving by ships. The size of the ships seems to preclude a stepwise transfer via the river systems between the Black Sea and the Baltic, but rather a travel over the Atlantic Sea. This calls for sea-worthy ships and knowledge in geography. In the Bronze Age, only the Mycenaean, Minoan and Phoenician cultures had such ships and such skill. Reaching this far north by 1750 BC in ships following the Atlantic coast of Europe implies that those people may as well have reached much further to the south and the west than previously assumed.
