Cataloguing remains Korres's team created a
computer database of all original pieces. By entering, in some cases, over 50 criteria
to identify each piece—among them height, width, slope, corrosion,
cracking, stain marks, and even graffiti—they hoped the computer could
aid them in finding each remnant's original position on the building. But often
differences in the pieces are so subtle that they must abandon the computer and
match fragments by eye.
