The coordinates in the table below indicate nails used to stabalize the
mosaics where they were seperating from the structure above. There are
at least three different types of nail in evidence suggesting this type
of intervention was attempted at different times in the past.
The heads of these nails have been
painted to match
the mosaics with varying degrees of success.
From my perch atop the ciborium it was only the different heads
that distinguished them. The good ones are of copper though there are some
of iron that have caused problems.
An interesting sidelight to this mapping exercise was that a thermal
study done earlier showed the nails but not enough of the mosaics to
get a firm correlation. This survey should supply a solid geometric
reference against which to calibrate the other study.
