Aquae Mattiacae
Aquae Mattiacae or FONTES MATTIACI, a watering place with hot springs, in the country of the Mattiaci, that is, the district between the Maine and the Lahn. (Plin. Nat. 31.17; Amm. Marcell. 29.4.) The place is generally believed to be the same as the modern Wiesbaden, where remains of Roman bath-buildings have been discovered.
