From the mass of reference material, postcards, photostats of images in books, computer files sent from researchers in Rome, I would choose an image to draw. First there were charcoal drawings – drawn on the pages of an old cash book – the lines and margins over which the drawing was made approximating the lines of travertine blocks of the wall. I then remade the drawing in Indian ink. The smudge and grey of the charcoal had to be resolved into the sharp ‘yes’ or ‘no’ of the white of the paper and the black of the ink. This ink drawing was then traced into a computer and turned into a mathematical file, that could be enlarged or reduced as needed. This file was sent off to a factory outside Rome where the computer file was used to make a full-scale plastic stencil of the figure. The 40 cm drawing became a 10 m plastic stencil.
