The late Anonymous author edited by Banduri says that the wall of ancient Byzantium commenced at the Golden Horn near the gate of S. Eugenius to pass along by the Golden Milestone.[17] We place no reliance on the Anonymous for early history, but there is much to confirm Mordtmann’s view that an ancient wall occupied this position and that the Milion--which the Anonymous says was the land gate--was situated upon its course and formed indeed the entrance from the Street of Columns. This wall, which Mordtmann says passed on the land side of the old Serai in front of the modern museum (Tchenli Kiosk) where there is a high retaining wall, and continued to the west of S. Sophia not far from the narthex, we consider must be that which formed the landward inclosure of the Acropolis. The fourth region of the city, Mordtmann says, was separated from the second by the rock of the Acropolis and this wall. We are confirmed in our acceptance of the other wall described by Paspates as the seaward wall of the Acropolis, not only because it is built against the steep escarpment of the rock, but by finding that in the division of the city into the wards or regions of the _Notitia_ the first ward exactly comprised the space between the wall and the sea; the second region contained the old Acropolis itself, with a triangle of lower ground at the north against the Golden Horn, where was probably the sea gate; while the third was divided from the fourth by the great way which left the Milion gate on the old landward wall of the Acropolis. Such pre-existing features naturally formed the boundaries of the wards. We now give from the _Notitia Dignitatum_ the descriptions of the first four regions of the fourteen into which Constantine’s city was divided, which will show how Constantine occupied the old areas with the royal and public quarters of his new city. Twelve regions were included within the walls, and two others were formed by the suburbs of Blachernae and Galata. REGION I. Contains the house of Placidia Augusta; the house of most noble Marina; the Baths of Arcadius; 27 streets or alleys; 118 houses; 2 porticoes; 15 private baths; 4 public cornmills; 15 private cornmills; 4 terraces of steps. It is under one curator, who looks after the whole region; it has 1 vernaculus, a slave (or messenger) for all regions; 25 collegiati, who are selected from different Guilds (Corporati), and help at fires; and 5 street wardens, who watch the city at night. REGION II. Gradually rises with a gentle ascent beginning from the smaller theatre, and then descends abruptly to the sea. It contains the Great Church; the Ancient Church; the Senate; the Tribunal built with porphyry steps; the Baths of Zeuxippus; the theatre; the amphitheatre; 34 streets or alleys, 98 houses; 4 large porticoes; 13 private baths; 4 private cornmills; 4 terraces of steps. It had also 1 curator, 1 vernaculus; 35 collegiati, 5 street wardens. REGION III.
