Dumnonii the British population, suggesting an ancient connection of peoples along the western Atlantic seaboard. The Latin name for Exeter is Isca Dumnoniorum ("Water of the Dumnonii"). This oppidum (a Latin term meaning an important town) on the banks of I River Exe certainly existed prior to the foundation of the Roman city in about AD 50. "Isca" is derived from the Brythonic word for flowing water, which was given to the River Exe. This is reflected in the Welsh name for Exeter: "Caerwysg" meaning "fortified settlement on the river Uisc". Isca Dumnoniorum originated with a settlement that developed around the
Moridunum (Axminster) century and occupation continued until the end of the 4th. Moridunum (Axminster) Moridunum was a fort and small town in the Roman province of Britannia. Its remains are located at Woodbury Farm, immediately south of Axminster in the English county of Devon. The square fort was built at the intersection of two Roman roads, the Fosse Way and Durnovaria-Isca Dumnoniorum road, apparently in the 2nd century. Its ditch survives around much of the site. A civilian settlement soon grew up nearby, encouraged by the building of what has been interpreted as a large stone mansio for the provincial postal service.
