Germania, written by Cornelius Tacitus around 98, is an ethnographic work on the Germanic tribes outside the Roman Empire. Germania fits squarely within the tradition established by authors from Herodotus to Julius Caesar. Tacitus himself had already written a similar essay on the lands and tribes of Britannia in his Agricola. The Germania begins with a description of the lands, laws, and customs of the Germanic people; it then segues into descriptions of individual tribes, beginning with those dwelling closest to Roman lands and ending on the uttermost shores of the Baltic, among the amber-gathering Aesti, the primitive and savage Fenni, and the unknown tribes beyond them.
