high, yet entire in many places; at each angle there 

 is a circular tower, two others in each of the sides; 

 they rise much higher than the walls; the towers and 

 the walls constructed with very large blocks of cut 

 stone. To what use the hollow of the square had 

 been applied, I could form no conjecture; in it im- 

 mense blocks of cut stone, and segments of arches of 

 different dimensions, tumbled together in monstrous 

 heaps ; near to the gateway by which we entered, two 

 arches remain perfect, a third nearly so ; they were 

 probably carried all along the inside of (but distinct 

 at least twenty feet from) the wall. These arches 

 spring from very slender .pillars^ each pillar a single 

 shaft; the arches are nearly semicircular, of the same 

 beautiful white stone as the pillars. About a quarter 

 of a mile from this square there is another, which ap- 

 pears to be a fourth part less; the entrance into this 

 is under the loftiest as well as the widest arch of stone 

 J ever saw : I had no means of measuring, which I 

 much regretted : I cannot draw, which I regretted 

 much more. The proportions of the pillars, andof the 

 arch which they support, conveyed to me something 

 more just and beautiful than I can describe. The 

 inside of the arch is richly ornamented with sculp- 

 ture; at the sides there are niches, I suppose, for sta- 

 tues ; the outer face of the building is composed 

 of great blocks of stone as the greater square ; 

 and in many places yet entire, appear to be as well 

 chisseled and jointed as the best constructed mar- 

 ble building I ever saw, even at Venice. The 

 height of the wall seems to be equal to that of 

 the greater square ; the thickness, which from some
