Aesti

The Aesti (or Aestii) were a people described by the Roman historian Tacitus in his treatise Germania (ca. 98 CE). According to this account, the Aestii lived on the shore of the Suebian Sea (Baltic Sea), eastward of the Suiones (Scandinavians) and westward of the Sitones. They were a population of Suebia. Tacitus did not know whether to assign the nearby Fenni to Germania or Sarmatia (which extended as far west as the Vistula in places).
