This work is primarily devoted to the history of the Amber Lands in Roman times. It is based on archaeological data dating back to the beginning of the 1st millennium AD, and studies the local material and culture of this region. Geographically, the Amber Lands include the western outlying district of the southeast sector of the Baltic Sea littoral, or "Southeast Baltic". This part of Central Europe, limited by the lower reaches of the River Vistula in the west, and the Neman in the east, has a complex landscape formed in the Late Glacial. Dating to this historical period are the amber-bearing layers of glauconit ("blue ground"), covered by a mass of sandy soils carried by the glacier sweeping in from east Europe approximately 2 million years ago.
