Road station
Viaca
Memmingen
Viaca was a station on the road from Lake Constance to Augsburg, probably at Memmingen in Bavaria, though Krumbach has also been suggested and a modern atlas leaves it unlocated. It may be the Viana listed by the Greek geographer Ptolemy. On the map it lies twenty-three Roman miles from Vemania and twenty from the next station, whose name is lost. The road on to Augsburg is drawn as two stretches, and a small hole in the parchment breaks the first of them.
