great Distance from the City, above all the Houses, we might easily discover, that the Walls built by _Constantine_ did not reach beyond this Pillar, which stood about half a Mile’s distance from the _Church_ of the _Apostles_. I saw this Pillar took to Pieces, and remov’d for building a Mosque, by Order of _Solyman_ the Emperor. The _Base_, the _Pedestal_ and the Foundation of it were of white Marble. The Foundation-Stone alone was so high, that I could not climb it without a Ladder. The _Pedestal_ was four Foot and nine Digits high, and the _Plinth_ one Foot, and six Digits. The _Greeks_ and the _Turks_, each in their Dialect, call’d it the _Pillar_ of the _Virgin_, which I take to be that celebrated by our modern Writers, which they say was erected upon a Hill, and supported the Statue of _Venus_, carv’d in Stone. When the _Ancient Description of the Wards_ tells us, that the eleventh _Ward_ is no Ways bounded by the Sea, it must be so understood as to mean, that the Plain situated between the Bay of _Ceras_, and the Foot of the fourth Hill, was not within the Walls, since the same _Treatise_ mentions, that the City was six thousand one hundred and fifty Foot broad; that is, a Mile and two hundred and thirty Paces; for the Latitude of the _Isthmus_, which stretches itself over the fourth and seventh Hill, thro’ which the old Wall extended itself, exceeds the Breadth abovemention’d. But _Zosimus_, an ancient Historian, says, that _Constantine_ the _Great_ so wholly surrounded the City with a Wall, that it cut off the _Isthmus_ from Sea to Sea. So that upon the whole, there is a Necessity to place the Plain, situate between the Bay, and the Bottom of the fourth Hill, in the tenth _Ward_. CHAP.
