Vistula (Polish name: Wisla) is the name of a river in central Europe. It is also Poland's longest river; it is 1,091 kilometers (678 miles) long and drains about 192,000 square kilometers (74,000 sq. miles).
The name Vistula is Gothic and was recorded by Tacitus in 98 AD in his "Agricola and Germania". During that time the Vistula River ran into the Mare Suebicum, which was later called Baltic Sea. According to him, near the delta lived the East Germanic tribes of the Burgundians, on both banks the Goths and east of them the Aestii-Prussi, Galindi, Sudauer, Borusci, Veneti, Fenni-Finns, and more. However, Tacitus' knowledge of the different Germanic peoples was second-hand at best; as such, it should be taken with the proverbial grain of salt.
The Vistula river is only a short portage from the Dnieper River, and thence to the Black Sea. Boats could be rolled from one river to the next there. What later became the city of Kiev in the Ukraine was earlier known by its Gothic name of Danapirstadir "City on the Dnieper". The Baltic Sea-Vistula-Dneipir-Black Sea water route was one of the most ancient trade-routes, the Amber road, on which amber and other items were traded from Northern Europe to Greece, Asia, Egypt, and elsewhere.
