By means of the triangulation and the numerical analysis, we have calculated geometrical factors of the circular setting lines found on the 6th century part of the cornice of the main dome of Hagia Sophia. Our results are: 1) the two setting lines, one on the north, the other on the south, can be regarded as arcs of two different circles; 2) these arcs, geometrically accurate as they are, show a very slight undulation with rescect to the perfect arc; 3) the radius of the north setting line is 15.303 (±0.010)m and that of the south 15.307 (±0.005)m; 4) the north and south arcs are not concentric, the distance of their centers being 3.338m; 5) the error assessment about the measurement shows that these values are more reliable than those presented by Van Nice and Mainstone.
