The first traces of human settlement in the area of the city show evidence of linear pottery settlements dating from the early Neolithic period. Since the last pre-Christian centuries, members of the Celtic tribe of the Treveri settled in the area of today's Trier. The city of Trier derives its name from the later Latin locative "in Trēverīs" for earlier "Augusta Treverorum". According to the Archbishops of Trier, in the Gesta Treverorum, the founder of the city of the Trevians is Trebeta. German historian Johannes Aventinus also credited Trebeta with building settlements at Metz, Mainz, Basel, Strasbourg, Speyer and Worms.
