concentric with the ones said above and with the 
diameter similar to their radius, considering the relative 
root-mean-square deviation.

It can be highlighted that the circumference 
interpolated on the four piles relative to Sant'Aquilino is 
tangent to the four octagonal columns while the other 
three groups of four columns each have a distance from 
the interpolated circumferences of a maximum of 35 cm 
in the centreline. 
Figura 5 
Building the circumferences that interpolate the groups 
of columns of each sector of the tetraconco, you find 
out that it adheres perfectly to the columns but it 
crosses the curvilinear parts of the piles (fig. 5). 
The translation of three of the four circumferences 
doesn't change the geometry and the dimensions but it 
must be expanded with new hypothesis and 
elaborations considering the up-to-date results. 
Gathering the pile points and the curvilinear sector 
points worsens the outcome and the adjustment of the 
circumferences to reality. 
It is clear from these first deductions that the four 
interpolated circumferences of the exedras of the 
tetraconco are inscribed in another circumference 
perfectly tangent to the extrados of the sectors of the 
exedras. Even if this hypothesis could explain the layout 
operations and the project genesis, we must be careful 
and deepen our studies before drawing conclusions that 
have only a probability of being true. 
1.9 Archaeological and archaeometrical studies 
The archaeological and archaeometrical research has 
studied all the structures in a vertical sequence, from 
foundations to coverings. Thanks to the 
characterization of the various stonework techniques 
and to the stratigraphic analysis (fig. 6,7 e 8) of the 
walls of each part, many different construction stages 
have been isolated, grouped in periods and tested with 
radiocarboniol4 and thermoluminescence. Some 
original parts of the floor have also been put through 
the stratigraphic analysis, just like piles and supporting 
columns, as well as decorated surfaces (mosaics, 
frescos, plaster). 
All the building techniques of the walls, in stone or in 
brick, have been characterized and deepened with the 
description of texture, mensiochronologic and chemical- 
physical characteristics of the mortars. The single 
techniques have also been dated one by one. A 
cataloguing operation of all the details surveyed has 
been set. 
All the building stages have been historically defined in 
order to insert them in the three-dimensional model 
resulting from the survey, which will represent the 
structural evolution of the building and that will allow 
the reconsideration of what has been deducted from 
documentary sources, in the light of the last 
archaeological results. 
2. SURVEY COMPLETION AND ANALYSIS 
The plan at the women's gallery level, two principal 
sections and the model of one of the most complex 
sectors of the tetraconco has been arranged. 
All the data resulting from the survey, from the 
archaeometrical and material analysis, rendered 
numerically congruent in the space, will be gradually 
systematized in order to be processed in a GIS.
