exported amber through the Amber Road, and imported metals in return. During the time of the Nordic Bronze Age, metals, such as copper, tin and gold, were imported into Scandinavia on a massive scale. Copper was imported from Sardinia, Iberia and Cyprus. The trade network was briefly disrupted during the Late Bronze Age collapse in the 12th century BC. Evidence for horse-drawn chariots appears in Scandinavia c. 1700 BC, around the same time as it appears in Greece. In both cases the chariots appear to have come from the region of the Carpathian Basin or the western steppe. Chariot bits and whip handles in Denmark dating from this time feature the same curvilinear designs that are found on contemporary artefacts from the Carpathian Basin and in the elite shaft graves at Mycenae. These designs subsequently appear on Nordic Bronze Age metalwork, including on the gold disc of the Trundholm Sun Chariot. Depictions of chariots also appear in Scandinavian rock art dating from c. 1700, as they do on engraved stone stelae from Mycenae. The introduction of the chariot in Scandinavia coincided with the introduction of socketed spearheads, whose origin Vandkilde (2014) ascribes to the Seima-Turbino culture. During the 15th–14th centuries BC the Nordic Bronze Age and Mycenaean Greece shared the use of similar flange-hilted swords, as well as select elements of shared lifestyle, such as campstools, drinking vessels decorated with solar symbols, and tools for body care including razors and tweezers. This "Mycenaean package", including spiral decoration, was directly adopted in southern Scandinavia after 1500 BC, creating "a specific and selective Nordic variety of Mycenaean high culture" that was not adopted in the intermediate region of Central Europe. These similarities can not have come about without intimate contacts, probably through the travels of warriors and mercenaries. Archaeological evidence further indicates the existence in both regions of shared institutions linked to warriors. Specifically, the dual organisation of leadership between a Wanax and a Lawagetas in Mycenaean Greece was apparently replicated in the Nordic Bronze Age. However this dual organization may have also been part of a shared Indo-European tradition. Other similarities have been noted in artistic iconography from both regions and its associated cosmology. Some of the contacts between Scandinavia and Greece were probably conveyed through Central Europe. Trade and cultural contacts have also been noted between the Nordic Bronze Age and New Kingdom Egypt. The contacts during the Late Bronze
