There is little room for difference of opinion in regard to the point from which the seven miles are to be measured. That point could not have been in the Theodosian Walls, as the Hebdomon is mentioned before they were in existence. For a similar reason, it could not have been in the Wall of Constantine, seeing the Egnatian Road which led from Byzantium to Rome was marked with the seventh milestone before the foundation of Constantinople. It must, therefore, have been the point whence distances from old Byzantium were measured under the Roman domination. This being so, the choice lies between the Milion near St. Sophia, and the gate of Byzantium near the Column of Constantine. In favour of the former is the fact that it was the point from which distances from Constantinople were afterwards measured; for in all probability that usage was the continuation of the practice of the older city, any change in that respect being not only unnecessary, but exceedingly inconvenient. Still, the result will be substantially the same if the gate of Byzantium is preferred, since the Milion and that gate were at a short distance from each other. Seven miles from either point, westwards, to the Sea of Marmora will bring us to the modern suburb of Makrikeui. Between the promontory on which that village stands and the promontory of Zeitin Bournou, to the east, is a bay which could serve as a harbour; while to the north and north-east spreads a magnificent plain. Makrikeui, therefore, satisfies all the indications regarding the site of the Hebdomon.
