The Valley which divides the seventh from the six Hills of the _Promontory_, is an easy Descent. It extends itself in Length to the Distance of four thousand Paces, if you take in the Plain on the Sea Shore. If you exclude that, and take your Dimensions from the winding of the seventh Hill, ’tis not above three thousand three hundred Paces long. It lies so much upon a Level, that you cannot perceive by walking it, that it has the least Ascent; yet you may discover by the Discernment of the Eye that it sensibly lengthens and widens itself into a greater Breadth. It bounds the Sides of the third and the fifth Valley, and the lowest Eminences of the fifth and sixth Hills. It is full of Gardens and pleasant Meadows. Here the Soldiers sometimes act their Mock-Fights. There’s a Rivulet which runs through the Middle of it, which is often dry in Summer Time. CHAP. XVIII. _Of the seventh Hill._ The seventh Hill is called the _Xerolophos_, on which stands the Pillar of _Arcadius_. This Hill is little less than twelve thousand Paces in Circumference, and contains more than a third Part of the City. The other two Parts are comprehended in the Compass of the _Promontory_, which is above twenty thousand Paces in Circumference. By _Paces_, I would here be thought to mean the ordinary Steps we take in Walking, which I cannot exactly reduce to a just Mensuration with the _Roman Pace_, by reason of the Turnings and Windings of the Ways, and the Differences of Paces, which are longer or shorter, according to the different Ascents and Descents of the Ground we walk. This Hill makes the third Angle of the City, from whence _Constantinople_ is look’d upon to be of a triangular Figure. It lies shelving with a very moderate Descent, and has a double Declivity; one of which falls gently into the Valley, which divides the seventh Hill from the _Promontory_, and is of an equal Length with the Valley itself. The other Descent, which partly lies to the South-east, and partly to the South, falls into the _Propontis_, and is in some Places five hundred Paces steep, in others four hundred, three hundred, a hundred, nay even fifty, till it comes to the Point of the third Angle of the City, whence a large Plain shoots out towards the Sea, which, in different Places, is of a different Breadth. The Entrance of this Plain, at the Angle of the City just mention’d, is very narrow; it afterwards widens, which is occasioned by the Winding of one of its Sides, from whence it gently rises to the Foot of a small Hill, where ’tis four hundred Paces broad; onwards it is straiten’d into fifty, and afterwards is widen’d into a Breadth of a hundred Paces only. The End of this Plain, to the Distance of a thousand Paces, is more than four hundred Paces broad. On the Ridge of this Hill, there is a Plain of some Length and Breadth; the Hill itself is bounded by the Land Wall, and on the Top of it is a Cistern which is call’d _Mocisia_, which is wholly unroof’d,
