A humble, 6th-century glass bowl from Iran was found in Nara, Japan. From a shipwreck near Sumatra in Indonesia, divers recovered a 9th-century turquoise-glazed ceramic amphora from West Asia. There were luxury goods on display, too, including a spectacular 7th-century golden necklace found in the eastern Mediterranean with lapis lazuli from Afghanistan and rock crystal from Madagascar, and a remarkable set of 8th-century ivory chess pieces from South Asia discovered in Samarkand in Uzbekistan.
