; let 6031" be divided by 30.
For the apparent heights j ^L = 201" = apparent
modulus for the details
of the cornice.
Having determined the values of the two moduli, 0'0914 feet for the projections, and
201;/ for the apparent heights, then the details are figured in aliquot parts, as shown in Fig. 1.
The apparent heights of the details of the cornice = 8 + 2 + 5 + 6 + 9 = 30 apparent parts,
measured in seconds.
The horizontal projections of the Entablature = Bi + 17} + M + 3? + 3? — 31i horizontal
aliquot parts.
Plate XII., Fig. 2, and Plate XIII., Fig. 2, are sections of the Pediment cornices of the
Parthenon and of the Propylsea. In these sections we possess two very perfect
examples of a described arc of the conic sections.
Plate XII., Fig. 2. The soffit of the Pediment cornice of the Parthenon being the arc of a
parabola, with A for the vertex, then let AB be the diagonal of a parallelogram, whose
sides, AC, CB, are as 9 : 2 ; let AC — 9 = x, CB = 2 = y, and from these given elements
the parabola is described.
Plate XIII., Fig. 2. The soffit of the Pediment cornice of the Propylaea is traced as the arc of
a hyperbola, with A for the vertex; then let AB be the diagonal of a square, whose
sides AC = CB; let AC = 5, AD = 1 = a, DC = 6 = x, CB = 5 = y, and from these
given quantities the arc of the hyperbola is described.
The outlines of the Mouldings and of the Ornaments are all geometrically described
as the arcs of the conic sections, and have been already given in Chapter II.
THE COLOURING.
Colonel Leake, in his introduction to the " Topography of Athens," says—" There can
"be no stronger proof of the early civilization of Athens than the remote period to which its
' history is carried in a clear and consistent series. We have some reason to believe that
' Cecrops, an Egyptian, who brought from Sais the worship of Neith, was contemporary with
' Moses." And the close connection between the designs of the coloured Entablatures and
Ornaments of Egypt and of Greece, as shown in Plates I., II., and III., seems to confirm the
idea that an early intercourse existed between the two countries, and to lead us naturally to
expect that the early Doric Entablatures were relieved by colours, the same as the Entablatures
in Egypt, even if no remains existed; but on all the Doric Entablatures the traces of colours
are found, thus, on portions of the Entablature of the early Parthenon (possibly B.C. 800), now
