Scyllae
Scyllae (Tab. Peut.; Geogr. Rav. 4.6, 5.12), a town of Thrace, on the Euxine, where the long wall, erected by the emperor Anastasius Dicorus for the defence of Constantinople, terminated. This wall commenced at Selymbria, on the Propontis, and was carried across the narrow part of Thrace, at the distance of about 40 miles from Constantinople, its length being 2 days' journey, (Procop. de Aed. 4.9; Gibbon, Decline and Fall, 100.40.)
